or GND, depending on their inactive levels, to reduce power
Comments
A Low on this pin indicates that the CPU enters
either HALT or SLEEP mode because of
execution of either a HALT or SLP instruction.
The NMI input is a higher priority input than the
maskable interrupts. It is always recognized at
the end of an instruction, regardless of the state
of the interrupt enable control bits. This input
includes a Schmitt-trigger to allow RC rise times.
This external NMI signal is combined with an
internal NMI signal generated from the WDT
block before being connected to the NMI input of
the CPU.
