ASCIE — ATD Sequence Complete Interrupt Enable
0 = Disables ATD interrupt
1 = Enables ATD interrupt on Sequence Complete
The sequence complete interrupt function signals the MCU when a
conversion sequence is complete. At this time, the result registers
contain the result data generated by the conversion sequence. If this
interrupt function is disabled, then the conversion complete flags must
be polled to determine when a conversion or a conversion sequence
is complete. Note that reset clears pending interrupts.
ASCIF — ATD Sequence Complete Interrupt Flag
0 = No ATD sequence complete interrupt occurred
1 = ATD sequence complete interrupt occurred
The sequence complete interrupt flag. This flag is not cleared until the
interrupt is serviced (by reading the result data in such a way that the
conversion complete flag is cleared), a new conversion sequence is
initiated, or the module is reset. This bit is not writable in any mode.
