Reserved
The write value should always be 0.
Reserved
This bit is always read as 0 and cannot be modified.
These bits select the control mode of the interrupt
controller. For details of the interrupt control modes,
see section 5.5.1, Interrupt Control Modes and
Interrupt Operation.
00: Interrupt control mode 0 (Interrupt is controlled by
01: Setting prohibited
10: Interrupt control mode 2 (Interrupt is controlled by
11: Setting prohibited
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
Manual Reset Select
Enables or disables the MRES pin input.
0: The MRES pin input (manual reset) is disabled
1: The MRES pin input (manual reset) is enabled
Reserved
This bit is always read as 0 and cannot be modified.
RAM Enable
Enables or disables the on-chip RAM. The RAME bit
is initialized when the reset status is released.
