5.2.1.3 PCM Interface Characteristics
In the following the PCM interface characteristics that can be programmed in the PCM
interface registers are explained in more detail.
PCM Mode PMOD: PMD1, PMD0
The PCM mode primarily defines the actual number of PCM highways that can be used
for switching purposes (logical ports). 1, 2, or 4 logical PCM ports can be selected. Since
