3. Not all combinations of bus timing configuration values result in valid bus cycles. Please refer to the XA User Guide section on the External
4. When code is being fetched for execution on the external bus, a burst mode fetch is used that dows not have PSEN edges in every fetch
5. This parameter is provided for peripherals that have the data clocked in on the falling edge of the WR strobe. This is not usually the case
6. Please note that the XA-S3 requires that extended data bus hold time (WM0 = 1) to be used with external bus write cycles.
7. Applies only to an external clock source, not when a crystal is connected to the XTAL1 and XTAL2 pins.
8. WAIT should not change between these times.

widened by WAIT. V10 = 2 for WAIT associated with a code read cycle using PSEN. V10 = V8 for a data write cycle using WRL
and/or WRH. V10 = V7 – 1 for a data read cycle using RD. This means that a single clock data read cycle cannot be stretched using
WAIT. If WAIT is used to vary the duration of data read cycles, the RD strobe width must be set to be at least two clocks in duration.
