Function
Port 7 is a 4-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 7 outputs can be configured as push/
pull or open drain drivers. The input threshold of Port 7 is
selectable (TTL or special). Port 7 pins provide inputs/
outputs for CAPCOM2 and serial interface lines.

Port 9 is a 6-bit bidirectional open drain I/O port (provide
external pullup resistors if required). 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.
The following Port 9 pins also serve for alternate functions:
