9.1 SPE Mapper Register Descriptions
This section gives a brief description of each register bit and its functionality. The abbreviations after each register
indicate if the register is read only (RO), clear-on-read/clear-on-write (COR/COW), or read/write (R/W).
Table 144. SPE_VERSION_R, SPE Version and Identification Register (RO)
Table 145. SPE_ONESHOT, One-Shot (R/W)
Note:
In Table 122, the mask bits for these delta and event bits are in
Table 147
, state bits are in
Table 148
, and
monitor values are in

Bipolar Violation Error.
A single bipolar violation error for
DS3 output is transmitted each time this bit transitions from a
0 to 1.
Signal Fail Clear.
Allows the signal fail algorithm to be forced
into the normal state.
Signal Fail Set.
Allows the signal fail algorithm to be forced
into the failed state.
Signal Degrade Clear.
Allows the signal degrade algorithm
to be forced into the normal state.
Signal Degrade Set.
Allows the signal degrade algorithm to
be forced into the degraded state.
