5.2.1
SYSCR is an 8-bit readable/writable register that controls software standby mode, selects the
action of the UI bit in CCR, selects the NMI edge, and enables or disables the on-chip RAM.
Only bits 3 and 2 are described here. For the other bits, see section 3.3, 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.
