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 XC167 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. Each pin can be
programmed for input (output driver in high-impedance
state) or output (configurable as push/pull or open drain
driver). The input threshold of Port 6 is selectable (standard
or special).
The Port 6 pins also serve for alternate functions:
