(1)When a low signal is detected on XHOLD, all pending XINTF accesses are completed before the bus is placed in a high-impedance state.

(2)The state of XHOLD is latched on the rising edge of XTIMCLK.

(3)After the XHOLD is detected low or high, all bus transitions and XHOLDA transitions 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.

(4)Not production tested.
