20.2.2
LPWRCR is an 8-bit readable/writable register that performs power-down mode control.
LPWRCR is initialized to H'00 by a reset and in hardware standby mode. It is not initialized by a
manual reset or in software standby mode.
Bits 7 to 2—Reserved: The function of these bits differs between the H8S/2623 Group and
H8S/2626 Group.
For details see sections 21A.2.3, 21B.2.3, Low-Power Control Register (LPWRCR).
Bits 1 and 0—Frequency Multiplication Factor (STC1, STC0): The STC bits specify the
frequency multiplication factor of the PLL circuit.
