IO
Port 2 is an 8-bit bidirectional I/O port. It is bit-wise
programmable for input or output via direction bits. For a pin
configured as input, the output driver is put into high-
impedance state. Port 2 outputs can be configured as push/
pull or open drain drivers. The input threshold of Port 2 is
selectable (standard or special).
The following Port 2 pins also serve for alternate functions:
I/O CC8IO CAPCOM1: CC8 Capture Inp./Compare Output,
I
EX0IN Fast External Interrupt 0 Input (default pin)
I/O CC9IO CAPCOM1: CC9 Capture Inp./Compare Output,
I
EX1IN Fast External Interrupt 1 Input (default pin)
I/O CC10IO CAPCOM1: CC10 Capture Inp./Compare Outp.,
I
EX2IN Fast External Interrupt 2 Input (default pin)
I/O CC11IO CAPCOM1: CC11 Capture Inp./Compare Outp.,
I
EX3IN Fast External Interrupt 3 Input (default pin)
I/O CC12IO CAPCOM1: CC12 Capture Inp./Compare Outp.,
I
EX4IN Fast External Interrupt 4 Input (default pin)
I/O CC13IO CAPCOM1: CC13 Capture Inp./Compare Outp.,
I
EX5IN Fast External Interrupt 5 Input (default pin)
I/O CC14IO CAPCOM1: CC14 Capture Inp./Compare Outp.,
I
EX6IN Fast External Interrupt 6 Input (default pin)
I/O CC15IO CAPCOM1: CC15 Capture Inp./Compare Outp.,
I
EX7IN Fast External Interrupt 7 Input (default pin),
I
T7IN
CAPCOM2: Timer T7 Count Input
TRST 57
I
Test-System Reset Input. A high level at this pin activates
the XC161’s debug system.
Note: For normal system operation, pin TRST should be
held low.
