Note: The Power ON by UART Cmd option can be
used only when an external MCU controls the IS2083.
The following figure illustrates the UART interface between the IS2083 and an external
MCU. The external MCU can control the IS2083 over the UART interface and wake up the
module with the MFB and P0_0 pins.Figure 2-20. Host MCU Interface Over
UART
Perform the following steps to configure the power switch to power on using UART
command.
