(2) Anytime write and batch write
Note The 16-bit counter is not cleared upon a match between the 16-bit counter value and the CCR1 buffer
Remarks 1. The above flowchart illustrates an example of the operation in the interval timer mode.
The TTnCCR0 and TTnCCR1 registers in TMTn can be rewritten during timer operation (TTnCTL0.TTnCE 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
register value. It is cleared upon a match between the 16-bit counter value and the CCR0 buffer register
value.
In this mode, data is transferred at any time from the TTnCCR0 and TTnCCR1 registers to the CCR0 and
CCR1 buffer registers during timer operation (n = 0, 1).
