Pin Definitions and Functions
Input
Outp.
I
Reset Input with Schmitt-Trigger characteristics. A low-level
at this pin while the oscillator is running resets the
XC164SM.
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.
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 XC164SM 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.
43-48
IO
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:
CC16IO (CAPCOM2) CC16 Capture Inp./Compare Outp.,
EX5IN (Fast External Interrupt 5) Input (alternate pin B)
CC17IO (CAPCOM2) CC17 Capture Inp./Compare Outp.,
CC18IO (CAPCOM2) CC18 Capture Inp./Compare Outp.,
EX4IN (Fast External Interrupt 4) Input (alternate pin B)
CC19IO (CAPCOM2) CC19 Capture Inp./Compare Outp.,
CC20IO (CAPCOM2) CC20 Capture Inp./Compare Outp.
CC21IO (CAPCOM2) CC21 Capture Inp./Compare Outp.
Note: At the end of an external reset P9.4 and P9.5 also may
input startup configuration values
