13.25 SVCA_R Pointer Corruption
13.26 Performance Monitoring Circuitry Lock Up
Proprietary and Confidential to PMC-Sierra, Inc., and for its customers’ internal use.
Document No.: PMC-2011334, Issue 7
For ESEI: Because the TRIB_INT[x][y][z] bits are not affected by this issue, for ESEI
indication, the TRIB_INT[x][y][z] can be used. To do this the ESEE bit must be set to '1', and
PJE and NJE must be set to '0'.
For PJEI: The PJE[12:0] bit can be used.
For NJEI: The NJE[12:0] bit can be used.
For OVR and PEND: The OVR and PEND bits in RTOP 336 register 300AH can be used to
replace this function.
Pointer corruption may occur when configuring SONET/SDH payload in the SVCA_R block
from a concatenated stream to a channelized stream.
this issue.
1. Ensure the pointer is recalculated when the payload is configured.
2. After payload configuration.
The performance monitoring circuitry in the RHPP_R, SVCA_R, SHPI, RSEF, PIPM blocks
may lock up when the device is reset during a specific timing window.
After the TUPP 2488 device is powered up, read the LCML_TIP, SCML_TIP and HPOH_TIP
bits in register 001DH to ensure they are not set to ‘1’. If one or more of these bits are set to
‘1’, perform a hardware or software reset as follows:
Hardware Reset
Software Reset
o Set Diag_NDFREQ bit 5 to ‘1’ in “SVCA Diagnostic/Configuration” indirect register
o Clear Diag_NDFREQ bit 5 to ‘0’ in “SVCA Diagnostic/Configuration” indirect register
1. Wait at least 5 REFCLK (5x 12.86 ns) cycles.
2. Assert the RSTB pin (Pull it low)
3. Wait a minimum of 1 ms (Keep it low)
4. De-assert RSTB (Pull it high).
5. Read LCML_TIP, SCML_TIP and HPOH_TIP to ensure they are not set to ‘1’. If one

0x02.
or more of these bits are set to ‘1’, perform a hardware or software reset again.
