3.2.2
Bits 7 and 6—Reserved: Only 0 should be written to these bits.
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.
Bit 3—NMI Edge Select (NMIEG): Selects the valid edge of the NMI interrupt input.
Bits 2 and 1—Reserved: Only 0 should be written to these bits.
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.
