6.9 TIMER_ERR_07

Initial repeat counter has 1 less period than next repeats Module

Category

Function

TIMER

Description

When using the timer repeat counter mode, the first repeat will have 1 less count than the subsequent repeats because the following repeat counters will include the transition between 0 and the load value. For example if the TIMx.RCLD = 0x3 then 3 observable zero events would appear on the first repeat counter and 4 observable zero events would appear on the following repeat counter sequences.

Workaround

Set the initial RCLD value to 1 more than the expected RCLD, then in the ISR for the Repeat Counter Zero Event (REPC), set the RCLD to the intended RCLD value. For example, if intending to have 4 repeats, set the initial RCLD value to RCLD = 0x5, then in the timer ISR for the REPC interrupt, set RCLD = 0x4. Now all timer repeats will have the same number of zero/load events.
