4.7.1 MCU Host Bus Emulation Mode Signal Timing – Write Cycle
Figure 4.10 MCU Host Bus Emulation Mode Signal Waveforms – write cycle
Table 4.4 MCU Host Bus Emulation Mode Signal Timings – write 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.
