Reset input: When this pin is driven
low, the chip is reset. The type of
reset can be selected according to
the NMI input level. At power-on, the
NMI pin input level should be set
high.
Standby: When this pin is driven low,
a transition is made to hardware
standby mode.
Bus request: Used by an external
bus master to issue a bus request to
the H8S/2357 Group.
bus request signal used when an
internal bus master accesses
external space in the external bus-
released state.
Indicates that the bus has been
released to an external bus master.
Flash write enable:
Enables/disables flash memory
programming.
Nonmaskable interrupt: Requests a
nonmaskable interrupt. When this pin
is not used, it should be fixed high.
Interrupt request 7 to 0: These pins
request a maskable interrupt.
