I am designing the HW for a new product using the LPC54606J512BD100 as the real-time MCU. I am running into an issue that I hope you can help me with. I must have the method for ISP API set as USART which when I read the chapter in the User Guide on the boot process explains that it must be Flexcomm Interface 0 and specifically PIO0_29 and PIO0_30 must be USART_RXD and USART_TXD, respectively. I also have a requirement to rout out the ETM TRACE pins for firmware debug. The problem is that the assigned TRACEDATA and TRACEDATA pins are the same pins as the ISP UART RXD and TXD pins.
