Change_Local_tx_parameter (16 bit
data/variable) This instruction is to change the Local tx
parameters. It takes either 16 bit data or 16 bit
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
Generation
{
Send_ttiu ((0x00006000, 0x36, 0xA)
Wait_ttiu (change_ttiu , 0x00004000)
Change_Local_tx_parameter (0x0400) //
requesting to change the
tx parameters to
reference_1
@received_control=LRT
@temp=@received_control & 0x1111000 //
0x11110000 is the mask
data so that the
variable contains only
the control word of the
received ttiu.
Change_Local_tx_parameter(@temp)//
variable as input
@status= Local_ Tx_status_word
@temp=@status | @control
Send_ttiu(@temp,0x36,0xA)
}
Where “0x0400” is the control word of TTIU.
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
the LSB 16‐bit contains the status word and MSB
16 bits are ZEROS.
