TBnCR
(0x4001_0xx8)
8.5 Timer synchronous mode
Under development
This mode enables the timers to start synchronously.
If the mode is used with PPG output, the output can be applied to drive a motor.

TMPM330
Use of the timer synchronous mode is specified in TBnCR.
=“0”: Timers operates individually.
=“1”: Timers operate synchronously.
The channels are in two segments: channels TMRB0 through 3 and channels TMRB4 through 7.
If =“1” is set, the start timing is synchronized with TMRB0 and TMRB4. The start
timing of each channel, TBmRUN =”1,1”, is ignored.
(Note 1) The channels designated for synchronous output must be started by
TBmRUN=”1,1” before the start triggered by TMRB0 and TMRB4.
(Note 2) Set TBnCR to “0” unless the timer synchronous mode is used. The timer
synchronous mode keeps the other channels operation waiting until TMRB0, TMRB4 and
TMRB8 start operation.
(Note 3) TMRB0 and TMRB4 are the master clocks of the timer synchronous mode. Therefore,
their TBnSYNC bit must be set to “0”.
(Note 4) This mode cannot be applied to TMRB8 and TMRB9.
