Description
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 8.13.1 “Port configurations”
and Table 11 “Static characteristics” for details.
All pins have Schmitt trigger inputs.
Port 2 also provides various special functions as described below:
P2.0 — Port 2 bit 0.
ICB — Input Capture B. (P89LPC935/936)
DAC0 — Digital-to-analog converter output.
AD03 — ADC0 channel 3 analog input. (P89LPC935/936)
P2.1 — Port 2 bit 1.
OCD — Output Compare D. (P89LPC935/936)
AD02 — ADC0 channel 2 analog input. (P89LPC935/936)
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 — 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.
OCA — Output Compare A. (P89LPC935/936)
P2.7 — Port 2 bit 7.
ICA — Input Capture A. (P89LPC935/936)
P89LPC933_934_935_936
