______
NMI Interrupt
______
An NMI interrupt is generated when the input to the P85/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 P85 register (bit 5 at address
03F016).
This pin cannot be used as a normal port input.
Key Input Interrupt
If the direction register of any of P104 to P107 is set for input and a falling edge is input to that port, a key
input interrupt is generated. A key input interrupt can also be used as a key-on wakeup function for cancel-
ling the wait mode or stop mode. However, if you intend to use the key input interrupt, do not use P104 to
P107 as A-D input ports. Figure 1.11.11 shows the block diagram of the key input interrupt. Note that if an
“L” level is input to any pin that has not been disabled for input, inputs to the other pins are not detected as
an interrupt.
