MPI COMMAND STRUCTURE
This section details each MPI command. Each command is shown along with the format of any additional data bytes
that follow. For details of the filter coefficients of the form C

, refer to the
General Description of CSD Coefficients
section on page 56.
Unused bits are indicated by

s are not guaranteed when they are read.
*Default field values are marked by an asterisk. A hardware reset forces the default values.
1.
Deactivate (Standby State)
(00h)
MPI Command
In the Deactivated mode:
All programmed information is retained.
The Microprocessor Interface (MPI) remains active.
The PCM inputs are disabled and the PCM outputs are high impedance unless
signaling on the PCM highway is programmed (SMODE = 1).
The analog output (VOUT) is disabled and biased at 2.1 V.
The channel status (CS) bit in the SLIC I/O Direction and Channel Status Register is
set to 0.
2.
Software Reset
(02h)
MPI Command
The action of this command is identical to that of the RST pin except that it only operates on the
channels selected by the Channel Enable Register and it does not change clock slots, time slots,
PCM highways, or global chip parameters. See the note under the hardware reset command
that follows.
Hardware Reset
(04h)
3.
MPI Command
Hardware reset is equivalent to pulling the RST on the device Low. This command does not
depend on the state of the Channel Enable Register.
Note:
The action of a hardware reset is described in
Reset States
on page 31 of the section
