### Notes:

Clock Accuracy Factor:
Use SETAF to store a value from -99ppm to +99ppm.  The decimal part is NOT used.

A positive number will add clock cycles (when clock is slow).
A negative number will subtract clock cycles (Use when the clock is fast)

So for example is your clock looses 20 seconds in 30 days:
30 days = 2,592,000 seconds

ppm = 20 seconds / 2,592,000 seconds =  7.72e-6

So set 8 ppm with SETAF

#### Multi-Line PROG Mode:
- Decoding is performed in the emulation due to space limitations, making it slightly slower. Setting the speed to 32MHz significantly improves responsiveness.

Know issues:
- An END or .END. will be displayed at the beginning or end of a program.
- Executing CAT in PROG Multi line mode and press R/S and then SST or BST will show some issues.
