Bits 7 1: Reserved. These bits always read 0 and must be set to 0.
Bit 0 (IOSTP: I/O Stop): Controls transition to low-power mode (system stop mode).
IOSTP = 0: The SCA remains in its current operating mode and does not enter system stop mode.
IOSTP = 1:
mode, so once it is set to 1 to enter system stop mode, the IOSTP bit cannot be cleared to 0 except
by a reset. Figure 3.3 shows transition timing in system stop mode.
