All pullups are 20-
μA weak pullups, and all pulldowns are 20-μA weak pulldowns. The pullups and pulldowns are included to ensure
proper input logic levels if the terminals are left unconnected (pullups
→ logic 1 input; pulldowns → logic 0 input). Devices that drive
inputs with pullups must be able to sink 20
μA while maintaining a logic-0 drive level. Devices that drive inputs with pulldowns must be
able to source 20
μA while maintaining a logic-1 drive level.
(3)
Pull to VMID when analog input is in single-ended mode.
