Information

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. CHF is
cleared by reading STATUS while CHnF is set and then writing a 0 to the CHF bit.
Writing a 1 to CHF has no effect.
If another event occurs between the read and write operations, the write operation has no
effect; therefore, CHF remains set indicating an event has occurred. In this case, a CHF
interrupt request is not lost due to the clearing sequence for a previous CHF.
NOTE
The STATUS register should be used only in Combine mode.
