Function
Internal Reset Indication Output. This pin is set to a low level
when the part is executing either a hardware-, a software- or
a watchdog timer reset. RSTOUT remains low until the EINIT
(end of initialization) instruction is executed.
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 C161CS/JC/JI 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.
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 Port 6 pins also serve for alternate functions:
