Training_ERROR_COUNT
This instruction is for accessing the error count of the received Dwords. This gives
flexibility to the user to change the remote tx parameters to get the optimal link with
minimal errors.
Example:
Var32 @error_count
Generation
{
Send_ttiu ((0x00006000, 0x36, 0xA)
Wait_ttiu (change_ttiu , 0x00004000)
@error_count= Training_ERROR_COUNT;
If(@error_count<2)
{
Send_ttiu ((0x0000A000, 0x36, 0xA)
}
}
Reset_Training_ERROR_COUNT
During manual Tx_Training resetting error _count can be done using this command.
Example
:
Var32 @error_count
Generation
{
Send_ttiu ((0x00006000, 0x36, 0xA)
Wait_ttiu (change_ttiu , 0x00004000)
@error_count= Training_ERROR_COUNT;
If(@error_count<2)
{
Send_ttiu ((0x0000A000, 0x36, 0xA)
Rest_Training_Error_count
}
}
Change_Local_tx_parameter(16'b data/variable)

variable which represents the control word of the TTIU. When this command is given, the
32 bit data or 16 bit variable value is written to the constant variable memory location
(address location is 511)
Example
:
var32 @received_control
var32 @Status
var32 @ control=0x00100000
var32 @temp
