32-bit Multi-PHY mode: TMOD[1:0]

 

 

 

 

 

indicates the valid data bytes of TDAT[31:0].

 

 

 

 

 

During transmission, TMOD[1:0] should

 

 

 

 

 

always be “00” until the last double word is

 

 

 

 

 

transferred on TDAT[31:0]. TMOD[1:0]

 

 

 

 

 

specifies the valid bytes of TDAT when

 

 

 

 

 

TEOP is asserted:
