21A.2.4 Module Stop Control Register (MSTPCR)
MSTPCR, comprising three 8-bit readable/writable registers, performs module stop mode control.
MSTPCRA to MSTPCRC are initialized to H'3FFFFF by a reset and in hardware standby mode.
They are not initialized in software standby mode.
MSTPCRA/MSTPCRB/MSTPCRC Bits 7 to 0—Module Stop (MSTPA7 to MSTPA0,
MSTPB7 to MSTPB0, MSTPC7 to MSTPC0, MSTPD7 and MSTPD6): These bits specify
module stop mode. See table 21A-3 for the method of selecting the on-chip peripheral functions.
