Notes
1) _{This is the last chance for BREQ to trigger the indicated regain-sequence.}
Even if BREQ is activated earlier, the regain-sequence is initiated by HOLD going high.
Please note that HOLD may also be deactivated without the XC161 requesting the bus.
3) _{The CS outputs will be resistive high (pullup) before being driven inactive.}
5) _{The next XC161 driven bus cycle may start here.}
