Signal Name	Type	State During	Signal Description
Signal Name	Type	Reset	Signal Description
		Reset


SC00	Input or Output	Input	Serial Control 0—For asynchronous mode, this signal is
			used for the receive clock I/O (Schmitt-trigger input). For
			synchronous mode, this signal is used either for transmitter 1
			output or for serial I/O flag 0.
			Port C 0—The default configuration following reset is GPIO
			input PC0. When configured as PC0, signal direction is
			controlled through the port directions register (PRR0). The
PC0			signal can be configured as ESSI signal SC00 through the
			port control register (PCR0).
			This signal has a weak keeper to maintain the last state even
			if all drivers are tri-stated.

SC01	Input/	Input	Serial Control 1—For asynchronous mode, this signal is the
	Output		receiver frame sync I/O. For synchronous mode, this signal is
			used either for transmitter 2 output or for serial I/O flag 1.
			Port C 1—The default configuration following reset is GPIO
			input PC1. When configured as PC1, signal direction is
PC1	Input or Output		controlled through PRR0. The signal can be configured as an
			ESSI signal SC01 through PCR0.
			This signal has a weak keeper to maintain the last state even
			if all drivers are tri-stated.

SC02	Input/	Input	Serial Control Signal 2—Used for frame sync I/O. SC02 is
	Output		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 C 2—The default configuration following reset is GPIO
PC2	Input or Output		input PC2. When configured as PC2, signal direction is
			controlled through PRR0. The signal can be configured as an
			ESSI signal SC02 through PCR0.
			This signal has a weak keeper to maintain the last state even
			if all drivers are tri-stated.
