Timer Module (TIM16B8CV2) Block Description  
Write: Has no meaning or effect in the normal mode; only writable in special modes (test_mode = 1).  
The period of the first count after a write to the TCNT registers may be a different size because the write  
is not synchronized with the prescaler clock.

Timer Enable  
TEN  
0 Disables the main timer, including the counter. Can be used for reducing power consumption.  
1 Allows the timer to function normally.  
If for any reason the timer is not active, there is no ÷64 clock for the pulse accumulator because the ÷64 is  
generated by the timer prescaler.  
6
Timer Module Stops While in Wait  
TSWAI  
0 Allows the timer module to continue running during wait.  
1 Disables the timer module when the MCU is in the wait mode. Timer interrupts cannot be used to get the MCU  
out of wait.  
TSWAI also affects pulse accumulator.  
5
Timer Stops While in Freeze Mode  
TSFRZ  
0 Allows the timer counter to continue running while in freeze mode.  
1 Disables the timer counter whenever the MCU is in freeze mode. This is useful for emulation.  
TSFRZ does not stop the pulse accumulator.
