UART terminal

For UART communication, a through hole for CN_UART connector and check through hole (CN7) are mounted
on the board. When using UART communication, remove the jumper pin of ICS connection selection terminal
(ICS_SEL).
In the initial firmware, UART communication is set to use the ICS function.
Communication method: UART start-stop synchronization function
