NOTES:
1. Load capacitance for all outputs = 80pF.
2. Variables V1 through V13 reflect programmable bus timing, which is programmed via the Bus Timing registers (BTRH and BTRL).
Refer to the
XA User Guide for details of the bus timing settings.
V1)
This variable represents the programmed width of the ALE pulse as determined by the ALEW bit in the BTRL register.
V1 = 0.5 if the ALEW bit = 0, and 1.5 if the ALEW bit = 1.
