INPUT PCM OFFSET REGISTER (IPOF)

IOF9

IOF8

IOF7

IOF6

IOF5

IOF4

IOF3

IOF2

After Reset 00 (H)

IOF9/2

Input PCM Offset 9 to 2.

Associated with IOF1/0, these ten bits indicate the delay between PFS signal and the

first bit of the frame, for each input

OUTPUT PCM OFFSET REGISTER (OPOF)

OOF9

OOF8

OOF7

OOF6

IOF5

OOF 4

OOF3

OOF 2

After Reset 00 (H)

OOF9/2

Output PCM Offset 9 to 2.

Associated with OOF1/0 of complementary offset register, these ten bits indicate the

delay between bit 0 of the frame out going versus bit 0 of the frame incoming.

P1SH2

P1SH1

P1SH0

P0SH2

P0SH1

P0SH0

After Reset 00 (H)

P1SH2/0

PCM1 Shift 2 to 0.

This number (0 to 7) is added to Input PCM offset to obtain the total shift of the frame of

PCM1.

P0SH2/0

PCM0 shift 2 to 0.

This number (0 to 7) is added to Input PCM offset to obtain the total shift of the frame of

PCM0.

INPUT PCM SHIFT 2 (IPSH2)

P3SH2

P3SH1

P3SH0

P2SH2

P2SH1

P2SH0

After Reset 00 (H)

P3SH2/0

PCM3 Shift 2 to 0.

This number (0 to 7) is added to Input PCM offset to obtain the total shift of the frame of

PCM3.

P2SH2/0

PCM2 Shift 2 to 0.

This number (0 to 7) is added to Input PCM offset to obtain the total shift of the frame of

PCM2.

OUTPUT PCM SHIFT 1 (OPSH1)

P1E

P1SH2

P1SH1

P1SH0

P0E

P0SH2

P0SH1

P0SH0

After Reset 00 (H)

P1E

Output PCM1 Enable.

P1E = 0. PCM1 output is at high impedance.

P1E = 1. PCM1 output is enable.
