FUNCTIONAL DEVICE OPERATION

OPERATIONAL MODES

TRI-STATE REGISTER

The tri-state command is use to set the SPn or SGn input

node as high impedance (refer to Table 10). By setting the

Tri-State Register bit to logic [1], the input will be high

impedance regardless of the metallic command setting. The

comparator on each input remains active. This command

allows the use of each input as a comparator with a 4.0 V

threshold. The MCU may change or update the Tri-State
