PMCATST:
BYPASS:
Reserved:
The PMCATST bit is used to configure the analog portion of the S/UNI-8x155 for PMC's
manufacturing tests. The PMCTST bit can be cleared by setting CSB to logic one and
RSTB to logic zero or by writing logic zero to the bit.
The BYPASS bit forces the reference clock (REFCLK) to directly clock the channel’s
parallel-to-serial converter to generate the serial transmit stream (TXD+/-). BYPASS is
available for PMC manufacturing test purposes only.
The CSU is not held in reset when BYPASS is high. The CSU may be held in reset by
asserting the CSURESET register in the CSPI block.
The reserved bit must be programmed to logic zero for proper operation.
