Totem Pole Digital Output Mode

To be used as totem pole digital output, the circuit is either in State H (Force High) or in State L (Force Low) according to the applied digital level:

Applied digital level

Output State

HIGH

State H (Force High)

LOW

State L (Force Low)

A state transition from State U (Pull-Up) occurs when setting totem pole digital output mode after power ON or FPGA boot sequence.
