TIMER Module

Category

Functional

Function

TIMER re-enable may be missed if done close to zero event

Description

When using a TIMER in one shot mode, TIMER re-enable may be missed if done close to zero event. The HW update to the timer enable bit will take a single functional clock cycle. For example, if the timer's clock source is 32.768kHz and clock divider of 3, then it will take ~100us to have the enable bit set to 0 properly.

Workaround

Wait 1 functional clock cycle before re-enabling the timer OR the timer can be disabled first before re-enabling.

Disable the counter with CTRCTL.EN = 0, then re-enable with CTRCTL.EN = 1
