28.1.4 Sub-Chip Module Stop Control Registers BH, BL (SUBMSTPBH, SUBMSTPBL)
SUBMSTPB specifies on-chip peripheral modules to shift to module stop mode in module units.
Each module can enter module stop mode by setting the corresponding bit to 1.
• SUBMSTPBH
Bit Bit Name
Initial
Value
R/W Corresponding Module
7 SMSTPB15 1 R/W Reserved
The initial values should not be changed.
6 SMSTPB14 1 R/W Ethernet controller (EtherC)
5 SMSTPB13 1 R/W DMAC for Ethernet (E-DMAC)
4 SMSTPB12 1 R/W USB function module (USB)
This bit is valid only in the H8S/2472 Group.
