Notes:
1. For the sake of simplicity in describing the interface, Power and Ground nets are omitted from
2. The Power and Ground nets are connected directly to the eZ80L92 device.
Additional note: external capacitive loads on RD, WR, IORQ, MREQ, D0–D7 and A0–A23 should be
below 10pF to satisfy the timing requirements for the eZ80
pulled to either V
to reduce noise sensitivity. To prevent EMI, the EZ80CLK output can be deactivated via software in
the eZ80F91’s Peripheral Power-Down Register.
