This example describes how LPUART works in low-power Sleep mode.
In this example, Main clock is configured at 24MHz.
In low-power mode, SCLK provides the communication clock for LPUART, so that data
can be sent and received normally. Communication interruption can wake MCU up from
low-power mode. This routine will interrupt data receiving at the beginning, then enter
the Sleep mode, wake up MCU when receiving external data, print prompt messages,
and receive 10 bytes when the received data is printed using LPUART.
The running effect of the routine is that the chip will enter the low-power mode after
reset, and the upper computer will send data to wake up the chip, and then the prompt
message will be printed. When 10 data is received, it will be displayed sends the received
data to the upper computer.
The LPUART is configured as follow:
In order to make the program work, you must do the following :
