Function
When low, this LSI enters the power-
on reset state.
When low, this LSI enters the
manual reset state.
Output signal for the watchdog timer
overflow
If this pin needs to be pulled down,
use the resistor larger than
1 MΩ to pull this pin down.
Non-maskable interrupt request pin
Fix to high or low level when not in
use.
Maskable interrupt request pins
Selectable as level input or edge
input. The rising edge, falling edge,
and both edges are selectable as
edges.
Shows that an interrupt cause has
occurred. The interrupt cause can be
recognized even in the bus release
state.
