IO

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.1)

IO

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.
