Serial Control 0
Functions in either Synchronous or Asynchronous mode. For Asynchronous
mode, this signal is the receive clock I/O (Schmitt-trigger input). For
Synchronous mode, this signal is either for Transmitter 1 output or Serial I/O
Flag 0.
Port D 0
The default configuration following reset is GPIO. For PD0, signal direction is
controlled through the Port D Direction Register (PRRD).
This signal is configured as SC10 or PD0 through the Port D Control Register
(PCRD). This input is 5 V tolerant.
Serial Control 1
Functions in either Synchronous or Asynchronous mode. For Asynchronous
mode, this signal is the receiver frame sync I/O. For Synchronous mode, this
signal is either Transmitter 2 output or Serial I/O Flag 1.
Port D 1
The default configuration following reset is GPIO. For PD1, signal direction is
controlled through PRRD.
This signal is configured as SC11 or PD1 through PCRD. This input is 5 V
tolerant.
Serial Control Signal 2
The frame sync for both the transmitter and receiver in Synchronous mode,
and for the transmitter only in Asynchronous mode. When configured as an
output, this signal is the internally generated frame sync signal. When
configured as an input, this signal receives an external frame sync signal for
the transmitter (and the receiver in synchronous operation).
Port D 2
The default configuration following reset is GPIO. For PD2, signal direction is
controlled through PRRD.
This signal is configured as SC12 or PD2 through PCRD. This input is 5 V
tolerant.
