Change_Local_tx_parameter / changelocaltxparameter (16'b data/variable)
This instruction is to change the Local tx parameters. It takes either 16 bit data which
represents the control word of the TTIU or 16'b variable that represents control word of
the TTIU.
when this command is given ,32 bit data or variable value will be written in to a constant
variable memory location (address location is 511)
Example:
var32 @received_control
var32 @Status
var32 @ control=0x00100000
var32 @temp

Local_ Tx_status_word
This instruction is for getting the status of the local tx parameters for the previous
requested tx parameter change. This is a 32 bit word in which LSB 16‐bit contains status
word and MSB 16bits are ZEROS.
Set OOB_SpeedNeg_TX_TAT:Tx_training_analysis_time
This setting defines the time for Link analysis i.e time for counting errors in the received
dwords after this time trainer request for new attached tx_ph y change depending on
the error count in Auto Tx_training mode . This is a global setting.
