Default = 0x00 0000

DONE

Indicates valid count values reside in PSCNT[6:0].

0 = Invalid values in PSCNT[6:0]. (Default)

1 = Valid values in PSCNT[6:0].

PSCNT[6:0]

Registers the number of OWR samples from the start time to the time when the next

zero crossing is detected.

[15:6]

Reserved.

DIR

Set the zero-crossing edge direction which will stop PSCNT count.

0 = Stop count at negative to positive zero-crossing - Rising Edge. (Default)

1 = Stop count at positive to negative zero-crossing - Falling Edge.

CODE[4:0]
