NumTx 

1 byte 

0-255 

Number of bytes to transmit 

NumRx 

1 byte 

0-255 

Number of bytes to receive  

RxStartAddr 1 

byte 

 

Start address of returned data. Specifies on what 
transmitted byte the response is to be stored and 
returned. 

TxData 0-255 

bytes 

 

The data to be transmitted. The size is specified 
by NumTx  

 

If the number of bytes to receive is greater than number of bytes to transmit, then the 
firmware will pad with the necessary 0x00 bytes. This is in order to save time-
consuming transfer from PC to the programmer.
