Parameters
The MCP652 single, MCP655 dual and MCP659 quad have their CAL/CS inputs internally pulled down to V
This time ensures that the internal logic recognizes the edge. However, for the rising edge case, if CAL/CS is raised
before the calibration is complete, the calibration will be aborted and the part will return to low power mode.
For the MCP655 dual, there is an additional constraint. CAL
