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 3.2.2, System Control

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.
