Re: ROM-functions & internal RAM

Thanks very much!
But I don't know who I ought to believe:
- startup400.a51 writes:
     " org     68H
     wos_crit_count: DSB     1"
- High-Speed Microcontroller User's Guide: DS80C400 Supplement page 195
writes:
"entercritsection - enter critical section. This function increments the
variable wos_crit_count located in direct data memory at addres 6Bh."

68 or 6B? Where is the true?
