Interrupt Control Select Mode 1 and 0
These bits select the interrupt 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
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 overflows
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
