Description
Module Stop Bit 16
When this bit is set to 1, the supply of the clock to the
A/D_0 is halted.
0: A/D_0 operates
1: Clock supply to A/D_0 halted
Description
Reserved
These bits are always read as 0. The write value should
always be 0.

When either or both of these bits are set to 1, the
supply of the clock to the UBC is halted.
00: UBC operates
01: Setting prohibited
10: Setting prohibited
11: Clock supply to UBC halted
