Function
Port 8 is an 8-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 8 outputs can be configured as
push/pull or open drain drivers. The input threshold of Port 8
is selectable (TTL or special).
The following Port 8 pins also serve for alternate functions:
CC16IO
CC17IO
CC18IO
CC19IO
CC20IO
CC21IO
CC22IO
CC23IO
Port 6 is an 8-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 6 outputs can be configured as
push/pull or open drain drivers. The input threshold of Port 6
is selectable (TTL or special).
The Port 6 pins also serve for alternate functions:
CS0

BREQ
Non-Maskable Interrupt Input. A high to low transition at this
pin causes the CPU to vector to the NMI trap routine. When
the PWRDN (power down) instruction is executed, the NMI
pin must be low in order to force the C167CR to go into power
down mode. If NMI is high, when PWRDN is executed, the
part will continue to run in normal mode.
If not used, pin NMI should be pulled high externally.
