Function
Port 2 is a 7-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 following Port 2 pins serve for
alternate functions:
EX1IN
EX2IN
EX3IN
EX4IN
EX5IN
EX6IN
EX7IN
These external interrupts are only available in the C161O.
Port 5 is a 2-bit input-only port with Schmitt-Trigger char. The
pins of Port 5 also serve as timer inputs:
T4EUD
T2EUD
Digital Supply Voltage:
+ 5 V or + 3 V during normal operation and idle mode.
Digital Ground.
2.5 V during power down mode.
