When a low signal is detected on XHOLD, all pending XINTF accesses will be completed before the bus is placed in a high-impedance state.
The state of XHOLD is latched on the rising edge of XTIMCLK.
§
After the XHOLD is detected low or high, all bus transitions and XHOLDA transitions will occur with respect to the rising edge of XCLKOUT. Thus,
for this mode where XCLKOUT = 1/2 XTIMCLK, the transitions can occur up to 1 XTIMCLK cycle earlier than the maximum value specified.
