Hello, I am using STPM 32 for my metering application and UART interface to communicate with MCU. I am using optocouplers for isolation between analog STPM32 and digital uC section. In the datasheet, it has given that pins like EN, SYS and SCS should be used for proper configurations. However , I would like to have optimized circuit as I need to use less optocouplers to save the space. Please let me know whether these controlling pins can be pulled up without affecting STPM32 's operation ?
