Wait100usMultiples()

2.37.1

Description

This function performs a delay of 100 µs multiples. It clears the CPU clock divider SFR DIVIC, initializes the timers
according to the delay time, and uses IDLE state during the delay time. In case an unexpected resume event
occurs, the IDLE state will be left and the function remain in RUN state until the delay is elapsed. The total duration
of the delay can be determined by an offset time of 28 µs plus the multiplication of the input parameter value with
100µs. The maximum delay time is limited in practice by the watchdog timer, which may be reset by the application
prior to the function call.

Actions

• Set SFR DIVIC = 00
