should be below 10 pF to satisfy the timing requirements for the eZ80 ® CPU. All unused inputs
should be pulled to either V DD or GND, depending on their inactive levels to reduce power con-
sumption and to reduce noise sensitivity. To prevent EMI, the EZ80CLK output can be deacti-
vated via software in the eZ80F91’s Peripheral Power-Down Register.
