11.8.1
The TMR is enabled or disabled by setting the module stop control register. In the initial state, the
TMR is disabled. After the module stop mode is canceled, registers can be accessed. For details,
see section 22, Power-Down Modes.
11.8.2
If a timer counter clock pulse is generated during the T
takes priority, so that the counter is cleared and the write is not performed. Figure 11.10 shows
this operation.
