IO
Port 2 is an 8-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 2 is selectable (standard
or special).
The following Port 2 pins also serve for alternate functions:

CC8IO CAPCOM1: CC8 Capture Inp./Compare Output,
I
EX0IN Fast External Interrupt 0 Input (default pin)
P2.9 50

EX2IN Fast External Interrupt 2 Input (default pin)
P2.11 52

CC11IO CAPCOM1: CC11 Capture Inp./Compare Outp.,
I
EX3IN Fast External Interrupt 3 Input (default pin)
P2.12 53
I/O
CC12IO CAPCOM1: CC12 Capture Inp./Compare Outp.,
I
EX4IN Fast External Interrupt 4 Input (default pin)
P2.13 54

I
EX5IN Fast External Interrupt 5 Input (default pin)
P2.14 55
I/O
CC14IO CAPCOM1: CC14 Capture Inp./Compare Outp.,
I
EX6IN Fast External Interrupt 6 Input (default pin)
P2.15 56
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. For normal system operation, pin
TRST should be held low. A high level at this pin at the rising
edge of RSTIN activates the XC164CM’s debug system. In
this case, pin TRST must be driven low once to reset the
debug system.
