Freescale Semiconductor, Inc.  
Timer Interface Module (TIM)  
TSTOP — TIM Stop Bit  
This read/write bit stops the TIM counter. Counting resumes when  
TSTOP is cleared. Reset sets the TSTOP bit, stopping the TIM  
counter until software clears the TSTOP bit.  
1 = TIM counter stopped  
0 = TIM counter active  
NOTE: Do not set the TSTOP bit before entering wait mode if the TIM is required  
to exit wait mode.  
TRST — TIM Reset Bit  
Setting this write-only bit resets the TIM counter and the TIM  
prescaler. Setting TRST has no effect on any other registers.  
Counting resumes from $0000. TRST is cleared automatically after  
the TIM counter is reset and always reads as logic 0. Reset clears the  
TRST bit.  
1 = Prescaler and TIM counter cleared  
0 = No effect  
NOTE: Setting the TSTOP and TRST bits simultaneously stops the TIM counter  
at a value of $0000.  
PS2–PS0 — Prescaler Select Bits  
These read/write bits select either the TCLK pin or one of the seven  
prescaler outputs as the input to the TIM counter as Table 15-2  
shows. Reset clears the PS2–PS0 bits.
