LS5B User Manual 15. Design Requirement Boot strap signals as mentioned in the Table 7-1, should not be driven by external devices until the module (SoC) comes out of reset. This mandates implementation of appropriate power sequencing mechanism on base-board. That is, there has to be 150ms delay between Supplying power to LS module (SoC) and power to any other device on the base-board. Boot Strap Signal Description UART_TXD0 Can be driven logic low but should not be driven logic high.
