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 (all bits inverted)
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 31.25 μs 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 set to AGND and the corresponding transmit time slot
on DX is set in H.I.
E0..3=0: commands disabled on the corresponding channel 0..3
E0..3=1: commands enabled on the corresponding channel 0..3
PDR = 0: RAM is enabled also in power down.
PDR = 1: RAM is disabled in power down. In this way it’s possible to reduce the power
consumption in power down.
