Freescale Semiconductor
NOTE:
NOTE:
TSTOP — TIMA Stop Bit
Do not set the TSTOP bit before entering wait mode if the TIMA is
required to exit wait mode. Also, when the TSTOP bit is set and the timer
is configured for input capture operation, input captures are inhibited
until TSTOP is cleared.
TRST — TIMA Reset Bit
Setting the TSTOP and TRST bits simultaneously stops the TIMA
counter at a value of $0000.
PS[2:0] — Prescaler Select Bits
This read/write bit stops the TIMA counter. Counting resumes when
TSTOP is cleared. Reset sets the TSTOP bit, stopping the TIMA
counter until software clears the TSTOP bit.
Setting this write-only bit resets the TIMA counter and the TIMA
prescaler. Setting TRST has no effect on any other registers.
Counting resumes from $0000. TRST is cleared automatically after
the TIMA counter is reset and always reads as logic 0. Reset clears
the TRST bit.
These read/write bits select either the PTB2/TCLKA pin or one of the
seven prescaler outputs as the input to the TIMA counter as
Table 11-1
1 = TIMA counter stopped
0 = TIMA counter active
1 = Prescaler and TIMA counter cleared
0 = No effect
