PMCTST
PMCATST
PMCATST_2488
The PMCTST bit is used to configure the S/UNI-2488 for PMC's manufacturing tests. When
PMCTST is set to logic one, the S/UNI-2488 microprocessor port becomes the test access
port used to run the PMC "canned" manufacturing test vectors, and all analog blocks are
forced into IDDQ mode. The PMCTST can be cleared by setting CSB to logic one or by
writing logic zero to the bit.
The PMCATST bit is used to configure the analog portion of the S/UNI-2488 for PMC's
manufacturing tests. The PMCATST can be cleared by setting CSB to logic one or by writing
logic zero to the bit. Both PMCATST and PMCATST_2488 (bit 5 and 6) in this register must
be set to high for OC48 line side analog test. Only PMCATST needs to be set high for APS
analog test.
The PMCATST_2488 bit is used to configure the 2488 Mbit/s analog portion of the S/UNI-
2488 for PMC's manufacturing tests. The PMCATST_2488 can be cleared by setting CSB to
logic one or by writing logic zero to the bit. Both PMCATST and PMCATST_2488 (bit 5 and
6) in this register must be set to high for OC48 line side analog test.
