35.4.10 Registers updated from write buffers
35.4.10.1 CNTIN register update
The following table describes when CNTIN register is updated:
Table 35-183. CNTIN register update
When Then CNTIN register is updated
CLKS[1:0] = 0:0 When CNTIN register is written, independent of FTMEN bit.
FTMEN = 0, or
CNTINC = 0
At the next system clock after CNTIN was written.
FTMEN = 1,
SYNCMODE = 1, and
CNTINC = 1
By the CNTIN register synchronization.
