6.2.2
The standby control register 2 (STBCR2) is a readable/writable 8-bit register that controls the
operation of modules in the power-down mode. STBCR2 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.
