NOTES:

1. Use the MOV instruction to set the UDF register.

2. This bit is enabled when the MR2 bit in the TAiMR register (i=0 to 4) is set to "0" (the UDF register

causes increment/decrement switching) in event counter mode.

3. Set this bit to "0" when not using the two-phase pulse signal processing function.
