Pin Definitions and Functions
Symbol Pin Input Function
Num. Outp.
RSTIN 63 I
Reset Input with Schmitt-Trigger characteristics. A low level at
this pin while the oscillator is running resets the XC164CM.
A spike filter suppresses input pulses <10 ns. Input pulses
>100 ns safely pass the filter. The minimum duration for a
safe recognition should be 100 ns + 2 CPU clock cycles.
Note: The reset duration must be sufficient to let the hardware
configuration signals settle.
External circuitry must guarantee low level at the
RSTIN pin at least until both power supply voltages
have reached the operating range.
NMI 64 I
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 XC164CM 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 9 is a 6-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 9 is selectable (standard or special).
The following Port 9 pins also serve for alternate functions:¹⁾
