Description
The PC1 pin can be used for GPIO. It can be
individually programmed as an input or output
and can also be used individually as an interrupt
input. Each Port C pin, when programmed as an
output, can be selected to be an open-drain or
open-source output. Port C is multiplexed with
one channel of the UZI interface.
The MOSI line is configured as an output when
the eZ80190 device is an SPI master device and
as an input when the eZ80190 device is an SPI
slave device. This signal is multiplexed with PC1.
The RxD1 pin is used by the UART to receive
asynchronous serial data. This signal is
multiplexed with PC1.
The SDA1 pin carries the I
signal is multiplexed with PC1.
The PC2 pin can be used for GPIO. It can be
individually programmed as an input or output
and can also be used individually as an interrupt
input. Each Port C pin, when programmed as an
output, can be selected to be an open-drain or
open-source output. Port C is multiplexed with
one channel of the UZI interface.
