9.2.21.1. Reading PMA Analog Parameters
Use attribute code 0x002C to read the analog parameter. Refer to the following table
for information on how to read the value.
Parameter Name
{0x85[7:0],0x84[7:0]}
GainLF
0x0901
CTLE LF Min
0x0909
CTLE LF Max
0x090A
GainHF
0x0900
CTLE HF min
0x0907
CTLE HF max
0x0908
GS1
0x0904
GS2
0x0905
RF_P2
0x0D00
RF_P2_MIN
0x0D09
RF_P2_MAX
0x0D0A
RF_P1
0x0D01
RF_P1_MIN
0x0D07
RF_P1_MAX
0x0D08
RF_P0
0x0D02
RF_B1
0x0D04
RF_B0
0x0D03
RF_B0T
0x200B
The value is returned on AVMM registers {0x89[7:0],0x88[7:0]}.
9.2.21.2. Updating PMA Analog Parameters
To write a new value to an analog parameter for the RX adaptation to use as the
starting value:
1. Use attribute code 0x002C to read the parameter value.
2. Use attribute code 0x006C to enter the new value on {0x85[7:0],0x84[7:0]} as a
two's complement number.
The analog parameter written is determined by the last previous analog parameter
read. Registers {0x89[7:0],0x88[7:0]} return 0x002C to indicate that the update was
successful.
9.2.21.3. Loading Parameters into the Receiver
After updating the analog parameter value, the parameters listed below need to be
loaded into the receiver to become effective. Use attribute code 0x00EC and the
following table to load the parameters into the transceiver.
