DSK5510 in HPI Multiplexed mode??

Hi,

Have a quick question on the DSK5510 board.

The HMODE pin has a pull-up on the DSK5510 implying the HPI to be in non-multiplexed mode (refer page 18 in SPRS076O).

And when I turn on the power to the DSK board, connect the emulator and open CCS, and just let the

bootloader code run (without loading any C code .out file), it stays in a loop (shown below) where it keeps polling on the HPIC READY bit to set.

FF8196 a6513805                 MOV port(#03805h),T2
FF819A 7d800066                 AND #32768,T2,T2
FF819E 0406f5                   BCC #0xff8196,T2 == #0

My question is, if the HPI is in non-multiplexed mode, then why is the code even waiting for

a bit in the HPIC register to get set?

Thanks,

Regards,

Aditi.
