Section 3 MCU Operating Modes
Bits 5 and 4—Interrupt Control Mode 1 and 0 (INTM1, INTM0): These bits select the control
mode of the interrupt controller. For details of the interrupt control modes, see section 5.4.1,
Interrupt Control Modes and Interrupt Operation.
0
1
Bit 3—NMI Edge Select (NMIEG): Selects the valid edge of the NMI interrupt input.

1
Bit 2— Reserved: Only 0 should be written to this bit.
Bit 1—Reserved: This bit is always read as 0 and cannot be modified.
Bit 0—RAM Enable (RAME): Enables or disables the on-chip RAM. The RAME bit is
initialized when the reset status is released. It is not initialized in software standby mode.
