JAJSCL2C October 2016 – August 2021 TPS65983B
PRODUCTION DATA
The TPS65983B UART paths (UART_RX/TX and LSX_P2R/R2P) and GPIO1/2 all have digital inputs that pass through a cross-bar multiplexer inside the digital core. Each of these pins is configurable as an input or output of the cross-bar multiplexer. The digital cross-bar multiplexer then connects to the port-data multiplexers as shown in Figure 9-35. The connections are configurable via firmware. The default state at power-up is to connect a buffered version of UART_RX to UART_TX providing a bypass through the TPS65983B for daisy chaining during power on reset.
