23.1.2  Module Stop Control Registers H and L (MSTPCRH, MSTPCRL) 
MSTPCR performs module stop state control. Setting a bit to 1, the corresponding module enters 
the module stop state, while clearing the bit to 0 clears the module stop state. 
•  MSTPCRH 
Bit  Bit Name  Initial Value  R/W  Module 
15  ACSE  0  R/W  All Module Clocks Stop Mode Enable 
Enables or disables all module clocks stop mode, 
in which, when the CPU executes a SLEEP 
instruction after the module stop state has been 
set for all the on-chip peripheral functions 
controlled by MSTPCR and EXMSTPCR or the 
on-chip peripheral functions except the TMR. 
0: All module clocks stop mode disabled 
1: All module clocks stop mode enabled 
14 MSTP14 0  R/W  EXDMA controller (EXDMAC)* 
13 MSTP13 0  R/W  DMA controller (DMAC) 
12  MSTP12  0  R/W  Data transfer controller (DTC) 
11  MSTP11  1  R/W  16-bit timer pulse unit 0 (TPU_0) 
10  MSTP10  1  R/W  Programmable pulse generator (PPG) 
9  MSTP9  1  R/W  16-bit timer pulse unit 1 (TPU_1) 
8  MSTP8  1  R/W  D/A converter (channels 2 and 3)
