Section 6 Power-Down Modes
6.2.4
STBCR4 is a readable/writable 8-bit register used to select whether or not individual modules
operate in power-down mode. STBCR4 is initialized (to H'00) by a power-on reset, but retains its
previous value after a manual reset or a period in the standby mode. Only byte access is valid.
