Hello
Iam Extremely new to assembly programming of code composer in event of using rtc interrupt i have some code in which the project is in large memory model and i am getting pretty intersting problems with the code taken from a demo project for the interrupt vecotrs
here i have attached the interrput vector assembly file 7612.rtc.asm which is throwing me problems
here below are the errors i am not able to resolve them
"../Delay-Testing/rtc.asm", REMARK at line 187: [R5672] If there is a long MMR
write with no
intervening single
MMR before this
return from
interrupt, then an
interrupted
conditional execution
may be corrupted;
(see the C55x silicon
exceptions errata;
Advisory CPU_94)
return_int
"../Delay-Testing/rtc.asm", REMARK at line 187: [R5674] If processor is in
fast-return mode, and
this return from
interrupt instruction
is stalled in the
ADDRESS or ACCESS1
phase, then the
execution of a
subsequent
conditional execution
may be corrupted;
(see the C55x silicon
exceptions errata;
Advisory CPU_99)
return_int
"../Delay-Testing/rtc.asm", REMARK at line 187: [R5675] An MMR write to the
RPTC register that is
close to this return
from interrupt
instruction may cause
an interrupted single
repeat loop's
execution to be
corrupted; (see the
C55x silicon
exceptions errata;
Advisory CPU_100)
return_int
COOL i hav overcomed this by reading Advisory CPU_100 and in assembly file edited this code
@RPTC_L=pop()||mmap()
nop
nop
nop
nop
nop
nop
before retrun_int
this solved the problem
