13.11Initializing the S/UNI-QUAD

The S/UNI-QUAD defaults to the Asynchronous Transfer Mode (ATM) operation but it is recommended to implement the following initialization sequence.

1.Reset the device. This can be done by asserting the RSTB pin or setting the RESET bit in the Master Reset and ID Register (Register 00).

2.Set the TPOP Path Signal Label (Register 0x48 ) to 0x13, which indicates an ATM payload.

3.For every channel, reset all the Rx and Tx ATM FIFO’s by setting the

FIFORST register bit in the TXCP and RXCP blocks. Keep this bit set for at least 1 μs, then set the bit back to its inactive logic zero value.

4.For every channel, reset the performance monitoring counters in TXCP and RXCP blocks, and preferably in all the blocks. The easiest way to do this is to use the TIP register bit.

13.12Using the S/UNI-QUAD with a 5 Volt ODL

The S/UNI-QUAD defaults to a 3.3V PECL optical data link (ODL) module interface. It can also be used with a 5V ODL. This is accomplished by setting to logic 1 the PECLV bit located in the Master Configuration Register (Register 0x01). Notice that all four channels are reconfigured.
