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).
17.9, NMI Input Disabling Conditions.
2. Only 0 can be written, to clear flags.
