function.
TBU_SetPrescCount16
Void TBU_SetPrescCount16 (TBU_CasPresc
TBU_CasPrescvalue_P, unsigned int Counter_Value)
Selects the prescalar value for the PWMART timer and the
counter values to be loaded into the TBU and ART regis-
ters.ART counter is enabled.
TBU_CasPrescvalue_P
where P is the prescalar division factor and it can be 1, 2,
4, 8, 16, 32 ,64, 128.
Counter_value
16 bit counter value. This value can be from 0000 to
FFFFh.
None
1. TBU_Init must have been called.
2. Cascaded mode must be selected
3. You must calculate the TBU_CasPrescValue_P and
Counter_Value for the required delay.
TBU_Enable must be called immediately after this func-
tion to get more accurate delay.
