24.1.1
The power-down state is controlled by the SBYCR, LPWRCR, TCSR (WDT1), and MSTPCR
registers. Table 24.3 summarizes these registers.

Notes: 1. Lower 16 bits of the address.
24.2
24.2.1
SBYCR is an 8-bit readable/writable register that performs power-down mode control.
SBYCR is initialized to H'00 by a reset and in hardware standby mode. It is not initialized in
software standby mode.
