Bits 31:0 – COMP[31:0] Compare Value

The 32-bit value of COMP0 is continuously compared with the 32-bit COUNT value. When a match occurs, the Compare 0 interrupt flag in the Interrupt Flag Status and Clear register (INTFLAG.CMP0) is set on the next counter cycle, and the counter value is cleared if CTRLA.MATCHCLR is '1'.
