13 Operation
13.1 Software Initialization Sequence
Using the following software initialization sequence puts the S/UNI-JET in a normal power
consumption state. PMC-Sierra™ strongly recommends using this reset sequence to guarantee the
device’s long term reliability.
Note: After a reset, the S/UNI-JET may start using more power than is required. While the
device’s normal operations are not altered, the excessive power consumption can cause the device
to give off high levels of heat, which in turn, could lead to future problems with the device.
To initialize the device:
•
•
Reset the S/UNI-JET.
Set IOTST (bit 2) in the Master Test Register (datasheet pg. 291) to '1' (by writing 00000100
to register 400H).
•
•
Put the S/UNI-JET Receive Cell Processor (RXCP) into test mode by writing:
