Table 1 Pin definitions
Reset Input with Schmitt-Trigger characteristics. Resets the
device when a low level is applied for a specified duration while
the oscillator is running. An internal pullup resistor enables
power-on reset using only a capacitor connected to
a bonding option, the RSTIN pin can also be pulled-down for
512 internal clock cycles for hardware, software or watchdog
timer triggered resets
Internal Reset Indication Output. This pin is set to a low level
when the part is executes hardware-, software- or watchdog
timer reset. RSTOUT remains low until the EINIT (end of ini-
tialization) 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.
If it is not used, NMI should be pulled high externally.
An 8-bit bidirectional I/O port. Port 6 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.
