______
NMI Interrupt
______
An NMI interrupt is generated when the input to the P77/NMI pin changes from “H” to “L”. The NMI interrupt
is a non-maskable external interrupt. The pin level can be checked in the port P77 register (bit 7 at address
03ED16).
This pin cannot be used as a normal port input.
