(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 TAAnCCR0 and TAAnCCR1 registers in TAAn can be rewritten during timer operation (TAAnCTL0.TAAnCE
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 TAAnCCR0 and TAAnCCR1 registers to the CCR0
and CCR1 buffer registers during timer operation.
