(2) Anytime write and batch write
Note The 16-bit counter is not cleared upon a match between the value of the 16-bit counter and the value of
Remarks 1. The above flowchart illustrates an example of the operation in the interval timer mode.
The TQnCCR0 to TQnCCR3 registers can be rewritten in the TMQn during timer operation (TQnCTL0.TQnCE
bit = 1), but the write method (anytime write, batch write) of the CCR0 to CCR3 buffer registers differs
depending on the mode.
(a) Anytime write
the CCRb buffer register. It is cleared upon a match between the value of the 16-bit counter and the
value of the CCR0 buffer register.
In this mode, data is transferred at any time from the TQnCCR0 to TQnCCR3 registers to the CCR0 to
CCR3 buffer registers during the timer operation (n = 0, 1).
