Note Before transmission is started, be sure to set to 1 when the SOLmn bit of the target channel is set to 0, and
set to 0 when the SOLmn bit of the target channel is set to 1. The value varies depending on the
communication data during communication operation.
Remarks 1. m: Unit number (m = 0), n: Channel number (n = 0), q: UART number (q = 0), mn = 00
2. : Setting disabled (set to the initial value)
×: Bit that cannot be used in this mode (set to the initial value when not used in any mode)
0/1: Set to 0 or 1 depending on the usage of the user
