JTAG and ZDI clock input.
Active High trigger event indicator.
JTAG data input pin. Functions as
ZDI data I/O pin when JTAG is disabled.
JTAG data output pin.
Power Supply.
This pin can be used for GPIO. It can be
individually programmed as input or
output and can also be used individually
as an interrupt input. Each Port D pin,
when programmed as output, can be
selected to be an open-drain or open-
source output. Port D is multiplexed with
one UART.
This pin is used by the UART to transmit
asynchronous serial data. This signal is
multiplexed with PD0.
This pin is used by the IrDA encoder/
decoder to transmit serial data. This signal
is multiplexed with PD0.
