Equalization Debug Monitor Status Register @0xe54

All the Dynamic Equalization information is captured in this Register.This is implemented using a synchronous FIFO, which stores all the captured events as sepereate 32 bit entries. Every read increments the read pointer and the client must store the data read. The FIFO can be cleared using the 'Clear all Capture bit in the EQ Debug Monitor Control Register.

Bits SW Name Description Reset
17:0 R Coefficients [EQCOEFF]
  • Phase0: Stores Initial Local TX Coefficients mapped from Initial Preset.
  • Phase1: Stores Initial Remote Coefficients advertised in Phase1. (Cp, LF, FS), EP Ph2/RC.
  • Phase2: Stores Coefficients Received from Remote Device.
  • Phase3: Stores CurrentCoefficients of the Remote Device. EP Ph3/RC.
 0x0
21:18 R Preset [EQPRE]
  • Phase0: Stores Initial Local TX Preset received in Phase0.
  • Phase1: Stores Initial Remote Preset advertised in Phase1. EP Ph2/RC.
  • Phase2: Stores Preset Received from Remote Device.
  • Phase3: Stores Current Preset of the Remote Device. EP Ph3/RC.
 0x0
22 R Preset Valid [EQPREVD] 1: Preset Valid, Indicates [21:18] is valid.
  • Phase0: Set to '1' to indicate that the intial Local Preset is Valid.
  • Phase1: Set to '1' to indicate that the advertised Remote Preset is Valid. EP Ph2/RC.
  • Phase2: Reflects the use preset bit received from the remote end.
  • Phase3: Set to 1 if controller provide preset feedback and to 0 for coefficient feedback. EP Ph3/RC.
 0x0
23 R Coefficient Reject [COEFFREJ]
  • Phase0: Set to '1' if an unsupported preset is received in Phase0.
  • Phase1: Set to '0' since no reject in phase1. EP Ph2/RC.
  • Phase2: Indicates that Controller Rejected the received settings to Remote Device in the TX TS1/TS2. This Reject indicates the current Coefficients or Preset received from Remote Device are rejected.
  • Phase3: Indicates Reject by the Remote end device. This bit indicates that the current Coefficient or Preset was rejected by the remote end device. EP Ph3/RC.
 0x0
29:24 R Direction Feedback [DIRFED] EP Ph2/RC Ph3: Stores Direction Change Feedback or Preset feedback Transmitted to Remote Device. Bit-22, EQPREVD, indicates if this is a Preset feedback or Direction Change Feedback. EP Ph3/RC Ph2: Reserved 0x0
31:30 R Equalization Phase [EQPHASE] Equalization Phase during Capture
  • 00 : Phase 0,
  • 01 : Phase 1,
  • 10 : Phase 2,
  • 11 : Phase 3.
