21.2
The H8/3048 Group has a system control register (SYSCR) that controls the power-down state,
and a module standby control register (MSTCR) that controls the module standby function. Table
21.2 summarizes these registers.

Note: * Lower 16 bits of the address.
21.2.1
SYSCR is an 8-bit readable/writable register. Bit 7 (SSBY) and bits 6 to 4 (STS2 to STS0) control
the power-down state. For information on the other SYSCR bits, see section 3.3, System Control
Register (SYSCR).
