P1.7 — Port 1 bit 7. High current source.
AD04 — ADC0 channel 4 analog input. (P89LPC985)
T3EX — Timer/counter 3 external capture input.
MOSI — SPI master out slave in. When configured as master, this pin is output;
when configured as slave, this pin is input. (pin remap)
Port 2: Port 2 is an 8-bit I/O port with a user-configurable output type. During reset
Port 2 latches are configured in the input only mode with the internal pull-up
disabled. The operation of Port 2 pins as inputs and outputs depends upon the port
configuration selected. Each port pin is configured independently. Refer to
7.16.1 “Port configurations”
All pins have Schmitt trigger inputs.
Port 2 also provides various special functions as described below:
P2.0 — Port 2 bit 0.
AD07 — ADC0 channel 7 analog input. (P89LPC985)
TXD — Transmitter output for serial port. (pin remap)
P2.1 — Port 2 bit 1.
AD06 — ADC0 channel 6 analog input. (P89LPC985)
RXD — Receiver input for serial port. (pin remap)
P2.2 — Port 2 bit 2.
MOSI — SPI master out slave in. When configured as master, this pin is output;
when configured as slave, this pin is input.
P2.3 — Port 2 bit 3.
MISO — SPI master in slave out. When configured as master, this pin is input,
when configured as slave, this pin is output.
P2.4 — Port 2 bit 4.
SS — SPI Slave select.
P2.5 — Port 2 bit 5.
SPICLK — SPI clock. When configured as master, this pin is output; when
configured as slave, this pin is input.
P2.6 — Port 2 bit 6.
SCL — I
P2.7 — Port 2 bit 7.
SDA — I
Port 3: Port 3 is a 2-bit I/O port with a user-configurable output type. During reset
Port 3 latches are configured in the input only mode with the internal pull-up
disabled. The operation of Port 3 pins as inputs and outputs depends upon the port
configuration selected. Each port pin is configured independently. Refer to
