TMS320VC5401 XF pin

Daniel Rosa Franzini

Hi all.

How can I access (set and reset) the XF pin in C using CCSv5? I have installed the CSP libraries but I could found any references to it.

Thank you.

XF is bit 13 of ST1 register. you can refer to C54x DSP Reference Set Apps Note.

I use this to toggle XF:

asm(" bit(ST1,#13) = #1 "); // toggle XF
asm(" bit(ST1,#13) = #0 "); // toggle XF

Regards.
