–

3.3/5

8fs PCM format (MSB-ﬁrst)

L: MSB-ﬁrst left-justiﬁed 32-bit, H: MSB-ﬁrst right-justiﬁed 24-bit

Note: In 8fs right-justiﬁed 24-bit format, there are a ﬁxed 32 bit clock

(F8BCK) cycles per word clock (F8WCK) cycle.

Note: In 8fs right-justiﬁed 24-bit format, the upper empty bits are for sign

extension.
