I/O 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 Section 4.1 “
Port configurations” and
the P89LPC932A1 data sheet, Static characteristics for details.
All pins have Schmitt triggered inputs.
Port 2 also provides various special functions as described below:
125I/OP2.0 — Port 2 bit 0.
I ICB — Input Capture B
226I/OP2.1 — Port 2 bit 1.
O OCD — Output Compare D
13 9 I/O P2.2 — Port 2 bit 2.
I/O MOSI — SPI master out slave in. When configured as master, this pin is
output; when configured as slave, this pin is input.
14 10 I/O P2.3 — Port 2 bit 3.
I/O MISO — When configured as master, this pin is input, when configured
as slave, this pin is output.
15 11 I/O P2.4 — Port 2 bit 4.
I SS
— SPI Slave select.
16 12 I/O P2.5 — Port 2 bit 5.
I/O SPICLK — SPI clock. When configured as master, this pin is output;
when configured as slave, this pin is input.
27 23 I/O P2.6 — Port 2 bit 6.
O OCA — Output Compare A
28 24 I/O P2.7 — Port 2 bit 7.
I ICA — Input Capture A
