Function
This is an 8-bit I/O port equivalent to P0. (Except that P60 to
P63's output type is N channel open drain only; P64 to P67's
output type is CMOS 3 state only; P60 to P63 no internal
pull-up registor support.) By software selecting, this port
can be used for I2C-BUS interface, UART0/UART1 input/
output pin, timerA3,A4 output pin. When P60 to P63 used as
I2C-BUS interface SDA,SCL, the input level of these pins are
CMOS/SMBUS selectable.
This is an 8-bit I/O port equivalent to P0. (Except that P70 to
P77 output type is N channel open drain only; no internal
pull-up registor support.) By software selecting, this port
can be used for external interrupt input pin, timerA0 to A3
and timer B5 input pin, PS2 interface input/output pin, I2C
interface (M306K9FCLRP only) or UART2 input/output pin.
P70 to P75 pins' level can be read regardless of the setting of
input port or output port.
P80 to P84, P86, and P87 are I/O ports with the same functions
as P0. (Except that P86 to P87's output type is CMOS 3 state
only; P80 to P84's output type is N channel open drain only;
P85 is input port only; the P80 to P84 and P85 are no internal
pull-up registor support.)
By software selecting, this port can be used for timer A4, B0 to
B2, I2C-BUS interface I/O pins. P86 and P87 can be set using
software to function as the I/O pins for a sub clock generation
circuit. In this case, connect a quartz oscillator between P86
(XCOUT pin) and P87 (XCIN pin). P85 is an input-only port that
______
also functions for NMI. The NMI interrupt is generated when
______
the input at this pin changes from “H” to “L”. The NMI function
cannot be cancelled using software.
This is an 8-bit I/O port equivalent to P0. (Except that output
type is CMOS 3 state only.) By software selecting, the port can
be used for external interrupt, timer B3 to B4, A-D converter
extended input pins, A-D trigger, SI/O3, SI/O4 I/O pins, PWM,
D-A converter output pins.
This is an 8-bit I/O port equivalent to P0. (Except that output
type is CMOS 3 state only.) If the ports are set to input
mode, the pull-up resistor can be set in bit unit. By software
selecting, the port can be used for A-D converter, external
interrupt input pins.
