Bits 4, 5 – MCx Match or Capture Channel x [x = 1..0]
This flag is set on a comparison match, or when the corresponding CCx register contains a valid capture value. This flag is set on the next CLK_TC_CNT cycle, and will generate an interrupt request if the corresponding Match or Capture Channel x Interrupt Enable bit in the Interrupt Enable Set register (INTENSET.MCx) is '1'.
Writing a '0' to one of these bits has no effect.
Writing a '1' to one of these bits will clear the corresponding Match or Capture Channel x Interrupt flag
In capture operation, this flag is automatically cleared when CCx register is read.
Bit 3 – SYNCRDY Synchronization Ready Interrupt Enable
Writing a '0' to this bit has no effect.
Writing a one to this bit will clear the Synchronization Ready Interrupt Disable/Enable bit, which disables the Synchronization Ready interrupt.
Value | Description |
---|---|
0 | The Synchronization Ready interrupt is disabled. |
1 | The Synchronization Ready interrupt is enabled. |
Bit 1 – ERR Error Interrupt Flag
This flag is set when a new capture occurs on a channel while the corresponding Match or Capture Channel x Interrupt flag is set, in which case there is nowhere to store the new capture.
Writing a '0' to this bit has no effect.
Writing a '1' to this bit clears the Error Interrupt flag.
Bit 0 – OVF Overflow Interrupt Flag
This flag is set on the next CLK_TC_CNT cycle after an Overflow condition occurs, and will generate an interrupt request if INTENCLR.OVF or INTENSET.OVF is '1'.
Writing a '0' to this bit has no effect.
Writing a '1' to this bit clears the Overflow Interrupt flag.
