Interrupt Control Select Mode 1 and 0
These bits select either of two interrupt control
modes for the interrupt controller.
00: Interrupt control mode 0
Interrupts are controlled by I bit.
01: Setting prohibited
10: Interrupt control mode 2
Interrupts are controlled by bits I2 to I0 and IPR.
11: Setting prohibited.
NMI Edge Select
Selects the input edge for the NMI pin.
0: Interrupt request generated at falling edge of NMI
input
1: Interrupt request generated at rising edge of NMI
input
Reserved
The initial value should not be changed.
