Registers description
Configuration register (CONF)
Addr=00h; Reset Value=3Fh
RES=0 Normal operation
RES=1 Device reset: I/0n and CSn are all inputs, DX is H.I. (equivalent to Hw. reset).
LIN=0 A or µ Law PCM encoding
LIN=1 Linear encoding (16 bits), two’s complement.
AMU=0 µ Law selection
AMU=1 A Law selection (even bits inverted)
STA=0 CS0 to CS3 scan the four SLICs connected to the I/O control port, each CS has a
31.25µs repetition time.
STA=1; I/O are static, CS0 to CS3 are configured as generic static I/O
PD3..0=0 CODEC 3..0 is active
PD3..0=1 CODEC 3..0 is in power Down. When one codec is in Power Down the
corresponding VFRO output is forced to AGND. and the corresponding transmit time slot on
DX is set in H.I.
