Port 1:
Port 1 is an 8-bit I/O port with a user-configurable output type,
except for three pins as noted below. During reset Port 1 latches are
configured in the input only mode with the internal pull-up disabled. The
operation of the configurable Port 1 pins as inputs and outputs depends
upon the port configuration selected. Each of the configurable port pins
are programmed independently. Refer to
Section 8.13.1 “Port
configurations”
and
Table 11 “Static characteristics”
for details. P1.2 and
P1.3 are open drain when used as outputs. P1.5 is input only.
All pins have Schmitt trigger inputs.
Port 1 also provides various special functions as described below:
P1.0 —
Port 1 bit 0.
TXD —
Transmitter output for the serial port.
P1.1 —
Port 1 bit 1.
RXD —
Receiver input for the serial port.
P1.2 —
Port 1 bit 2 (open-drain when used as output).
T0 —
Timer/counter 0 external count input or overflow output (open-drain
when used as output).
SCL —
I
2
C serial clock input/output.
P1.3 —
Port 1 bit 3 (open-drain when used as output).
INT0 —
External interrupt 0 input.
SDA —
I
2
C serial data input/output.
P1.4 —
Port 1 bit 4.
INT1 —
External interrupt 1 input.t
P1.5 —
Port 1 bit 5 (input only).
RST —
External reset input during power-on or if selected via UCFG1.
When functioning as a reset input, a LOW on this pin resets the
microcontroller, causing I/O ports and peripherals to take on their default
states, and the processor begins execution at address 0. Also used during
a power-on sequence to force ISP mode.
When using an oscillator
frequency above 12 MHz, the reset input function of P1.5 must be
enabled. An external circuit is required to hold the device in reset at
power-up until V
DD
has reached its specified level. When system
power is removed V
DD
will fall below the minimum specified
operating voltage. When using an oscillator frequency above
12 MHz, in some applications, an external brownout detect circuit
may be required to hold the device in reset when V
DD
falls below the
minimum specified operating voltage.
P1.6 —
Port 1 bit 6.
OCB —
Output Compare B. (P89LPC935/936)
P1.7 —
Port 1 bit 7.
OCC —
Output Compare C. (P89LPC935/936)
AD00 —
ADC0 channel 0 analog input. (P89LPC935/936)
