Notes: *External capacitive loads on RD, WR, IORQ, MREQ, D0–D7 and A0–A23 should be below 10 pF to satisfy
timing requirements for the eZ80 ® CPU.
All unused inputs should be pulled to either V
consumption and to reduce noise sensitivity.
To prevent EMI, the EZ80CLK output can be deactivated via software in the eZ80L92 Peripheral Power-Down
Register.
All inputs are CMOS level 3.3 V (5 V tolerant), except where otherwise noted.
