Table 19. Activating Status Register (RD5) (Continued)
Table 20. Activation State, Receiver AGC and FFE Step Gain Register (RD6)
RD6— Receiver Gain and State Machine Register
This 8-bit register holds the Analog AGC gain and FFE gain coefficients (AAGC and DAGC,
respectively). AAGC is the analog AGC from the IAFE, and DAGC is the Digital AGC in the
EDSP. Bit assignments are listed in
Bits ST0-ST2 indicate the current state of EMDP in the activation state machine as described in
