Power consumption on BF504B(no internal flash)

I put the BF504B into deep sleep mode and noticed the current on the 1.23v core was still at 7.75 mA.  This is 5.5mA higher then stated in Table 18, page 29 on the data sheet (chip temperature was around 75F).  I wonder if the 5.5mA comes from the JTAG circuit on the chip?  If the JTAG circuit was still active how much current would it draw on the 1.2V core theorectically?

 

Thanks,
