PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE
The ID bits can be read to provide a binary TUPP revision number.
The RESET bit allows the TUPP to be reset under software control. If the
RESET bit is a logic 1, the entire TUPP is held in reset. This bit is not self-
clearing. Therefore, a logic 0 must be written to bring the TUPP out of reset.
Holding the TUPP in a reset state places it into a low power, stand-by mode.
A hardware reset clears the RESET bit, thus negating the software reset.
Otherwise the effect of a software reset is equivalent to that of a hardware
reset.
