36.3.4 Interrupts
| Name | Vector Description | Conditions |
|---|---|---|
| CROSS | ZCD interrupt | Zero-cross detection as configured by INTMODE in ZCDn.INTCTRL and INVERT in ZCDn.CTRLA |
When a ZCD interrupt condition occurs, the CROSSIF flag is set in the Status (ZCDn.STATUS) register.
ZCD interrupts are enabled or disabled by writing to the INTMODE field in the Interrupt Control (ZCDn.INTCTRL) register.
A ZCD interrupt request is generated when the interrupt source is enabled, and the CROSSIF flag is set. The interrupt request remains active until the interrupt flag is cleared. See the ZCDn.STATUS register description for details on how to clear interrupt flags.
