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 Register (SYSCR).
SYSCR is initialized to H'01 by a reset and in hardware standby mode. It is not initialized in software standby mode.
