LPWRCR is an 8-bit readable/writable register that performs power-down mode control. The
following pertains to bits 1 and 0. For details of the other bits, see Section 24.2.3, Low Power
Control Register (LPWRCR). LPWRCR is initialized to H'00 by a power-on reset and in hardware
standby mode. It is not initialized in software standby mode.
