Hi,
I am using a TMS320C6711, I would want to use the 8-bit ROM boot configuration,
to such aim, I know that I must set up the HD[4:3] bits with 0 and 1 value
respectively. My problem is that I don't understand where to store this
values. Does a register exist?
Thanks in advance,
Thomas

Hi,
the HD[4:3] bits are fysical pins, not register values
(since they decide how the DSP boots, they have to be set to the correct
values before booting, so they can never be set in software)
on the 6713 DSK kit their values can be changed with jumpers
on the 6711 DSK i don't know
if you're making your own PCB, then you should provide the correct
pull-up or pull-down resistors to these pins
Check the datasheet of your DSP and look for the HD4 and HD3 terminals
on a 6713 it's pins C13 and C20 for a GDP/ZDP package and pins 156 and
154 for a pyp package
If you are making your own pcb, read the datasheet of the dsp!
(again) for the 6713, especially Table 18. Device Configurations Pins at
Device Reset (HD[4:3], HD8, HD12, and CLKMODE0) is very important
if you make mistakes with this your dsp won't boot properly and you
won't be able to fix this without a new pcb!
also, try to read and understand everything on the schematics of the DSK
boards, it provides very valueble information.
Hope this helps
