Remarks 1. The above flowchart illustrates an example of the operation in the interval timer mode.
The TPnCCR0 and TPnCCR1 registers in TMPn can be rewritten during timer operation (TPnCTL0.TPnCE bit
= 1), but the write method (anytime write, batch write) of the CCR0 and CCR1 buffer registers differs
depending on the mode.
(a) Anytime write
the CCR1 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 TPnCCR0 and TPnCCR1 registers to the CCR0 and
CCR1 buffer registers during timer operation (n = 0 to 3).
