http://mchp.us/12pB1XQ There are thirty special function registers in the PSMC configuration setup. Setting all thirty registers with the appropriate values for desired operation can be a daunting task. The PSMC Designer GUI was created to simplify that effort. The GUI divides the PSMC into up to eleven major functions. These functions are shown in relation to each other in block diagram format in the main GUI window. Clicking on a block opens the control GUI for that function. The user is guided through the PSMC configuration design by completing signal paths and control options within each function by selecting switch positions. Entry boxes for times and frequencies appear within the diagrams where incorporated by the function. https://www.microchip.com/8-bit
