bits in the TTIU. Giving the Change_TTIU command with mask value waits for any change
in the specified Bits in the Received TTIU compared to the previously received TTIU.
Example:
Generation
{
Wait_for_ttiu (change_ttiu , 0x00004000) //waiting for change in tx_init
bit of TTIU
Send_ttiu ((0x00006000, 0x36, 0xA)
Wait_for_ttiu (0x0000A000 , 0X00008000) //waiting for train comp bit to
go high
}

LRT: Last received TTIU
This instruction is for accessing the last received TTIU. The user can access the received
TTIU and reuse it as required.
Example:
{
@ttiu_mask=0x0006000
@ttiu=LRT
@ttiu_temp=@ttiu and @ttiu_mask
If(ttiu_temp=0006000)
{
Send_ttiu(0x0006000)
}
}
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.
