XRT83SL216
16-CHANNEL E1 SHORT-HAUL LINE INTERFACE UNIT
The serial microprocessor uses a standard 3-pin serial port with CS, SCLK, and SDI for programming the LIU.
Optional pins such as SDO, INT, and RESET allow the ability to read back contents of the registers, monitor
the LIU via an interrupt pin, and reset the LIU to its default configuration by pulling reset "Low" for more than
10µS. A simplified block diagram of the Serial Microprocessor is shown in
