(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 CCRb buffer
Remarks 1. The above flowchart illustrates an example of the operation in the interval timer mode.
The TABnCCR0 to TABnCCR3 registers can be rewritten in the TABn during timer operation
(TABnCTL0.TABnCE 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
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 TABnCCR0 to TABnCCR3 registers to the CCR0 to
CCR3 buffer registers during the timer operation.
