4.7.2 MCU Host Bus Emulation Mode Signal Timing – Read Cycle
Figure 4.11 MCU Host Bus Emulation Mode Signal Waveforms – read cycle
Table 4.5 MCU Host Bus Emulation Mode Signal Timings– read cycle
When Div By 5 is on the device will return 2 bytes when doing a read. When it is off the device will return
1 byte when doing a read. The clock period is 16.67 nS so most devices would need the Div By 5 to be
set on. IORDY can be held low permanently to extend all cycles.
