Patch Notes

  • Added DFLL out of bounds interrupt tracker (both xmtr and conv).

  • Added diagnostic and event logging when totalizer value decrease is detected.

  • Updated how displayed lists are handled when selection is being changed.

  • Updated pulse sequence to prevent pulse stoppage issues (on reboot for example):

    a. Corrected pulse last total conversion.

    b. Pulse output now checks that channel's total value increases on update.

  •  Added proper minimum value for pulse rate to avoid potential divide by zero error.

  • AMI exact read (mode 2) now uses correctly scaled total values.

  • Special value of 999 FT/S is now passed to daughter cards to denote empty pipe state (or error).

  • Updated CONFIG.SHOW to provide more information about system settings.
