The different modes of the Line Interface Block require the pin definitions to
change depending on the mode you are in. See Section 9 for exact definitions.
The following sections describe each mode
9.6.2.1 Direct Mode
This section defines how the Line Interface functions when in Direct Mode. The
Line interface does no processing on the any of the line signals but just passes
them between the 8 local links, which connect the A1SP and the 8 external lines.
In this mode the H-MVIP portions of the Line Interface Block are not used.
The type of line is selected based on the value of T1_MODE in the
LIN_STR_MODE memory register for each line. For unstructured data format
(UDF mode), the value of T1_MODE does not matter because data is interpreted
as a clear channel bit stream. If MVIP-90 mode is being used (MVIP_EN bit is
set in the LS_Ln_CFG_REG register for this line), then T1_MODE should be
inactive (‘0’).
