I am invoking the BSL on the MSP430FR4133 using the TEST and RST pins. After the RST line goes and then the TEST line goes low, I have found that I must wait 60 milliseconds before I can send data via the UART to the MSP430FR4133. I cannot find this delay specified in any of the data sheets. I can wait 60 milliseconds but want to find out the maximum amount of time that is required tp prevent variation from part to part.
