Section 5 Interrupt Controller

5.2.1
Bit
Initial value
Read/Write
SYSCR is an 8-bit readable/writable register of which bits 5, 4, and 2 select the interrupt control
mode and the detected edge for NMI.
Only bits 5, 4, and 2 are described here; for details on the other bits, see section 3.2.2, System
Control Register (SYSCR).
SYSCR is initialized to H'09 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 four
interrupt control modes for the interrupt controller. The INTM1 bit must not be set to 1.

Bit 2—NMI Edge Select (NMIEG): Selects the input edge for the NMI pin.
