INIT Initial Value Of The FTM Counter
39.3.9 Capture And Compare Status (FTMx_STATUS)
The STATUS register contains a copy of the status flag CHnF bit in CnSC for each FTM
channel for software convenience.
Each CHnF bit in STATUS is a mirror of CHnF bit in CnSC. All CHnF bits can be
checked using only one read of STATUS. All CHnF bits can be cleared by reading
STATUS followed by writing 0x00 to STATUS.
Hardware sets the individual channel flags when an event occurs on the channel. CHnF is
cleared by reading STATUS while CHnF is set and then writing a 0 to the CHnF bit.
Writing a 1 to CHnF has no effect.
If another event occurs between the read and write operations, the write operation has no
effect; therefore, CHnF remains set indicating an event has occurred. In this case, a CHnF
interrupt request is not lost due to the clearing sequence for a previous CHnF.
