controlled the LRDY line (e.g. after 2 waitstates, see figure 27 and 28).
until the bus cycle is complete, then drive it low again. By inserting predefined waitstates
the first LRDY sample point can be shifted to a time, where the peripheral has safely

Notes:
- MCTC wait state configuration is assumed to one cycle in this figure
- LRDY is evaluated the first time with the clock cycle following the MCTC related wait states
- Transaction is terminated one clock cycle after detecting LRDY active
- LRDY is evaluated only if LRDY-control is enabled
