Port 3 is a 13-bit bidirectional I/O port. Each pin can be
programmed for input (output driver in high-impedance
state) or output (configurable as push/pull or open drain
driver). The input threshold of Port 3 is selectable (standard
or special).The following Port 3 pins also serve for alternate
functions:
T6OUT [GPT2] Timer T6 Toggle Latch Output,
RxD1 [ASC1] Data Input (Async.) or Inp./Outp. (Sync.),
EX1IN [Fast External Interrupt 1] Input (alternate pin A),
TCK [Debug System] JTAG Clock Input
CAPIN [GPT2] Register CAPREL Capture Input,
TDI [Debug System] JTAG Data In
T3OUT [GPT1] Timer T3 Toggle Latch Output,
TDO [Debug System] JTAG Data Out
T3EUD [GPT1] Timer T3 External Up/Down Control Input,
TMS [Debug System] JTAG Test Mode Selection
T4IN [GPT1] Timer T4 Count/Gate/Reload/Capture Inp
TxD1 [ASC0] Clock/Data Output (Async./Sync.),
BRKOUT [Debug System] Break Out
T3IN [GPT1] Timer T3 Count/Gate Input
T2IN [GPT1] Timer T2 Count/Gate/Reload/Capture Inp
BRKIN [Debug System] Break In
MRST0 [SSC0] Master-Receive/Slave-Transmit In/Out.
MTSR0 [SSC0] Master-Transmit/Slave-Receive Out/In.
TxD0 [ASC0] Clock/Data Output (Async./Sync.),
EX2IN [Fast External Interrupt 2] Input (alternate pin B)
RxD0 [ASC0] Data Input (Async.) or Inp./Outp. (Sync.),
EX2IN [Fast External Interrupt 2] Input (alternate pin A)
SCLK0 [SSC0] Master Clock Output / Slave Clock Input.,
EX3IN [Fast External Interrupt 3] Input (alternate pin A)
CLKOUT System Clock Output (= CPU Clock),
FOUT Programmable Frequency Output
