4.1
The port handler is the interface between the serial ports and the chip internal protocol
functions. It converts incoming serial data into parallel data for further internal processing
and in the outgoing direction it converts parallel data into a serial bit stream.
4.1.1
The serial interface of the device can be configured in a 16-port mode and additionally
in a 28-port mode. The 16-port mode provides a clock pin, a data pin and a frame
synchronization pin for each port and direction. The 28-port mode provides a clock pin
and a data pin per port and direction. In this mode frame boundaries are indicated by
clock gaps. Table 4-1 and Figure 4-1 respectively show the pin configuration and the
supported frame structures in the 16-port mode and the 28-port mode.
