FTMx_CnSC field descriptions
Description
This read-only field is reserved and always has the value zero.
Channel Flag
Set by hardware when an event occurs on the channel. CHF is cleared by reading the CSC register 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.
0 No channel event has occurred.
1 A channel event has occurred.
Channel Interrupt Enable
Enables channel interrupts.
0 Disable channel interrupts. Use software polling.
1 Enable channel interrupts.
Channel Mode Select
Used for further selections in the channel logic. Its functionality is dependent on the channel mode. See
Table 39-7.
