RTX166: HLDEN BIT CLEARED BY OS


Information in this article applies to:

  • RTX166 Version 3.10a

QUESTION

RTX166 V3 appears to clear the HLDEN bit in the PSW. My application needs to use external bus arbitration. Is there a time when the HLDEN bit can be set but not cleared by RTX166?

ANSWER

This was a problem in RTX166 Version 3 which has been corrected in RTX166 Version 4. The context switch routines were not using the correct mask value when resetting the PSW.
