TMS320F28377D: Question on Baud rate calculation for SCI

Part Number: TMS320F28377D

Hello,

       I am trying to use the SCI function in TMS320F28377D. From the document SPRUHM8F  page 2006, Table19-3, for baud rate of 9600, the BRR value should be 650 based on the formula, However, 650 in hex should be '0x28A', I don't understand what does that 1616h mean. And I tried to use 0x16 for SCIHBAUD and 0x16 for SCILBAUD, it does't work. If I use 0x28A for the registers, the communication works, but sometimes with a lot of wrong data. I am guessing the baud rate is not quite matching between the two devices . Could anyone explain what does 1616h mean and how can I make my baud rate precise? Thank you!
