5.0 Pin Descriptions
COP8SAx I/O structure minimizes external component
requirements. Software-switchable I/O enables designers
to reconfigure the microcontroller’s I/O functions with a
single instruction. Each individual I/O pin can be indepen-
dently configured as an output pin low, an output high, an
input with high impedance or an input with a weak pull-up
device. A typical example is the use of I/O pins as the
keyboard matrix input lines. The input lines can be pro-
grammed with internal weak pull-ups so that the input
lines read logic high when the keys are all up. With a key
closure, the corresponding input line will read a logic zero
since the weak pull-up can easily be overdriven. When
the key is released, the internal weak pullup will pull the
input line back to logic high. This flexibility eliminates the
need for external pull-up resistors. The High current op-
tions are available for driving LEDs, motors and speakers.
This flexibility helps to ensure a cleaner design, with less
external components and lower costs. Below is the gen-
eral description of all available pins.
V
CC and GND are the power supply pins. All VCC and
GND pins must be connected.
CKI is the clock input. This can come from the Internal
R/C oscillator, external, or a crystal oscillator (in conjunc-
tion with CKO). See Oscillator Description section.
RESET is the master reset input. See Reset description
section.
The device contains four bidirectional 8-bit I/O ports (C,
G, L and F), where each individual bit may be indepen-
dently configured as an input (Schmitt trigger inputs on
ports L and G), output or TRI-STATE under program
control. Three data memory address locations are allo-
cated for each of these I/O ports. Each I/O port has two
associated 8-bit memory mapped registers, the CON-
FIGURATION register and the output DATA register. A
memory mapped address is also reserved for the input
pins of each I/O port. (See the memory map for the
various addresses associated with the I/O ports.)
Figure 5
shows the I/O port configurations. The DATA and CON-
FIGURATION registers allow for each port bit to be indi-
vidually configured under software control as shown be-
low:

Port L is an 8-bit I/O port. All L-pins have Schmitt triggers on
the inputs.
Port L supports the Multi-Input Wake Up feature on all eight
pins. The 16-pin device does not have a full complement of
Port L pins. The unavailable pins are not terminated. A read
operation these unterminated pins are not terminated. A read
operation these unterminated pins will return unpredictable
values. To minimize current drain, the unavailable pins must
be programmed as outputs.
Port G is an 8-bit port. Pin G0, G2–G5 are bi-directional I/O
ports. Pin G6 is always a general purpose Hi-Z input. All pins
have Schmitt Triggers on their inputs. Pin G1 serves as the
dedicated WDOUT WATCHDOG output with weak pullup
if WATCHDOG feature is selected by the ECON register.
The pin is a general purpose I/O if WATCHDOG feature is
not selected. If WATCHDOG feature is selected, bit 1 of the
Port G configuration and data register does not have any
effect on Pin G1 setup. Pin G7 is either input or output
depending on the oscillator option selected. With the crystal
oscillator option selected, G7 serves as the dedicated output
pin for the CKO clock output. With the internal R/C or the
external oscillator option selected, G7 serves as a general
purpose Hi-Z input pin and is also used to bring the device
out of HALT mode with a low to high transition on G7. There
are two registers associated with Port G, a data register and
a configuration register. Using these registers, each of the 5
I/O pins (G0, G2–G5) can be individually configured under
software control.
Since G6 is an input only pin and G7 is the dedicated CKO
clock output pin (crystal clock option) or general purpose
input (R/C or external clock option), the associated bits in the
data and configuration registers for G6 and G7 are used for
special purpose functions as outlined below. Reading the G6
and G7 data bits will return zeroes.
The device will be placed in the HALT mode by writing a “1”
to bit 7 of the Port G Data Register. Similarly the device will
be placed in the IDLE mode by writing a “1” to bit 6 of the
Port G Data Register.
Writing a “1” to bit 6 of the Port G Configuration Register
enables the MICROWIRE/PLUS to operate with the alter-
nate phase of the SK clock. The G7 configuration bit, if set
high, enables the clock start up delay after HALT when the
R/C clock configuration is used.

Port G has the following alternate features:

G5 SK (MICROWIRE Serial Clock)
G4 SO (MICROWIRE Serial Data Output)
G3 T1A (Timer T1 I/O)
G2 T1B (Timer T1 Capture Input)
G0 INTR (External Interrupt Input)
Port G has the following dedicated functions:
G7 CKO Oscillator dedicated output or general purpose
input
G1 WDOUT WATCHDOG and/or CLock Monitor if WATCH-
DOG enabled, otherwise it is a general purpose I/O
Port C is an 8-bit I/O port. The 40-pin device does not have
a full complement of Port C pins. The unavailable pins are
not terminated. A read operation on these unterminated pins
will return unpredictable values. Only the COP8SAC7 device
contains Port C. The 20/28 pin devices do not offer Port C.
On these devices, the associated Port C Data and Configu-
ration registers should not be used.
Port F is an 8-bit I/O port. The 28-pin device does not have
a full complement of Port F pins. The unavailable pins are
not terminated. A read operation on these unterminated pins
will return unpredictable values.
