Chip Select 256 Enable
Enables or disables P97/WAIT/CS256 pin function in
extended mode.
0: P97/WAIT pin
1: CS256 pin
IOS Enable
Enables or disables AS/IOS pin function in extended
mode.
0: AS pin
1: IOS pin
These bits select the control mode of the interrupt
controller. For details on the interrupt control modes,
see section 5.6, Interrupt Control Modes and Interrupt
Operation.
00: Interrupt control mode 0
01: Interrupt control mode 1
10: Setting prohibited
11: Setting prohibited
External Reset
This bit indicates the reset source. A reset is caused
by an external reset input, or when the watchdog timer
overflows.
0: A reset is caused when the watchdog timer
1: A reset is caused by an external reset.
NMI Edge Select
Selects the valid edge of the NMI interrupt input.
0: An interrupt is requested at the falling edge of NMI
1: An interrupt is requested at the rising edge of NMI
Description
WAIT pin function is selected by the settings of
WSCR and WSCR2.
Outputs low when a 256-kbyte expansion area of
addresses H'F80000 to H'FBFFFF is accessed.
Outputs low when an external area is accessed.
Outputs low when an IOS expansion area of
addresses H'FFF000 to H'FFF7FF is accessed.
