Section 5 Interrupt Controller
5.2
5.2.1
SYSCR is an 8-bit readable/writable register that selects the interrupt control mode, and the
detected edge for NMI.
Only bits 5 to 3 are described here; for details of the other bits, see section 3, MCU Operating
Modes.
SYSCR is 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 one of two
interrupt control modes for the interrupt controller.

Bit 3—NMI Edge Select (NMIEG): Selects the input edge for the NMI pin.

Bit 1—IRQ Input Pin Select (IRQPAS): Selects switching of the pins that can be used for input
of IRQ4 to IRQ7. IRQ4 to IRQ7 input is always performed from one of the ports.
