† _{Bit 1 = MSB = sign bit and is clocked in first on PCM IN or clocked out first on PCM OUT. Bit 8 = LSB = least significant bit and is clocked in}
last on PCM IN or is clocked out last on PCM OUT.
NOTE A: All timing parameters are referenced to VIH and VIL except tpd8 and tpd9, which references the high-impedance state.
