I/O

Port 2 is a 16-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 (TTL or special).

The following Port 2 pins also serve for alternate functions:

CC0IO

CAPCOM1: CC0 Capture Inp./Compare Output

CC1IO

CAPCOM1: CC1 Capture Inp./Compare Output

CC2IO

CAPCOM1: CC2 Capture Inp./Compare Output

CC3IO

CC12IO

CAPCOM1: CC12 Capture Inp./Compare Outp.,

EX4IN

Fast External Interrupt 4 Input

CC13IO

CAPCOM1: CC13 Capture Inp./Compare Outp.,

EX5IN

Fast External Interrupt 5 Input

CC14IO

CAPCOM1: CC14 Capture Inp./Compare Outp.,

EX6IN

Fast External Interrupt 6 Input

CC15IO

CAPCOM1: CC15 Capture Inp./Compare Outp.,

EX7IN

Fast External Interrupt 7 Input,

T7IN

CAPCOM2: Timer T7 Count Input

Note: During Sleep Mode a spike filter on the EXnIN

interrupt inputs suppresses input pulses <10 ns.

Input pulses >100 ns safely pass the filter.
