System Control Register (SYSCR)
SYSCR is an 8-bit readable/writable register that selects the interrupt control mode, controls the
LWR pin, switches the IRQ
initialized to H'01 by a reset, and in hardware standby mode. It is not initialized in software
standby mode.
Bits 5 and 4—Interrupt Control Mode 1 and 0 (INTM1, INTM0): These bits select either of
two interrupt control modes for the interrupt controller. For details, see section 5, Interrupt
Controller.
Bit 3—NMI Edge Select (NMIEG): Selects the input edge for the NMI pin. For details, see
section 5, Interrupt Controller.
Bit 2—LWR Output Disable (LWROD): Enables or disables LWR output. For details, see
section 9.16, Port F.
Bit 1—IRQ Port Switching Select (IRQPAS): Selects switching of input pins IRQ
