received.

PC4

Input or

Output

Port C 4ÑThe default configuration following

reset is GPIO input PC4. When configured as

PC4, signal direction is controlled through

PRR0. The signal can be configured as an ESSI

signal SRD0 through PCR0.

STD0

Input/

Output

Input

Note: This signal has a weak keeper to maintain the last

state even if all drivers are tri-stated.

Serial Transmit DataÑSTD0 is used for

transmitting data from the serial transmit shift

register. STD0 is an output when data is being

transmitted.

PC5

Input or

Output

Port C 5ÑThe default configuration following

reset is GPIO input PC5. When configured as

PC5, signal direction is controlled through

PRR0. The signal can be configured as an ESSI

signal STD0 through PCR0.

Note: This signal has a weak keeper to maintain the last

state even if all drivers are tri-stated.
