PCML
PCM Analog Loopback.
0 = Normal operation.
1 = Enables analog data to be received from the line, converted to digital data and trans-
mitted across the ISOcap link. The data passes through the RX filter and is looped back
through the TX filter and is transmitted back out to the line.
5PCME
PCM Enable (Registers 34–37 should be set before PCM transfers are enabled).
0 = Disable PCM transfers.
1 = Enable PCM transfers.
4:3
PCMF[1:0]
PCM Data Format.
00 = A-Law. Signed magnitude data format (refer to Table 23 on page 46).
01 = -Law. Signed magnitude data format (refer to Table 22 on page 45).
10 = 8-bit linear. The top 8-bits of the 16-bit linear signal are transferred, and the bottom
8-bits are discarded (2s complement data format).
11 = 16-bit linear (2s complement data format).
2
Reserved
Always write this bit to zero.
1PHCF
PCM Highway Clock Format.
0 = 1 PCLK per data bit.
1 = 2 PCLKs per data bit.
0TRI
Tri-state Bit 0.
0 = Tri-state bit 0 on positive edge of PCLK.
1 = Tri-state bit 0 on negative edge of PCLK.
