Why do you think so? any justification? I am simulating CTS/RTS
handsake using PF's and using PF0 for RTS. With #defined LABELS I can
change the interrupt channel (A or B) with minimal code changes.

my apologies for not providing the complete information. Once am done
with writing all the registers, I call a function "fosHwiAdd" to
register the interrupt provided by the Fusion RTOS . I am running my
application on Fusion RTOS. This API will sets IMASK, IAR, IVG for me.

No problems in using BlackFin programmable flags.
