28.4.5 Start, Stop and Reset Events
To enable the counter/timer, the ON bit of the TUxyCON0 register must be set. When ON =
0
, the module is disabled, and the module output is cleared. When the module is disabled, the following things apply:
- RUN SFR bit is cleared.
- OPOL bit in the TUxyCON0 register will continue to control the output polarity.
- ERS input logic is reset and disabled.
- Interrupts will not trigger.
- Clock requests are not asserted.
- All SFRs can be written.
Important:
- The value of the TUxyTMR counter and TUxyCR capture registers are not affected when the ON bit is clear, unless they are changed explicitly by the user.
- Clock synchronization may apply, in which case, actions performed may or may not have immediate effect.
- The ON bit, like many other bits in the module, remains unchanged after a non-POR/BOR system Reset. It is recommended to clear the ON bit at the start of program execution to avoid starting the system with a running timer.
