Caution For the UART reception, be sure to set the SMRmr register of channel r to UART Transmission
mode that is to be paired with channel n.
Remarks 1. m: Unit number (m = 0, 1), n: Channel number (n = 1, 3), mn = 01, 03, 11, 13
r: Channel number (r = n − 1), q: UART number (q = 0 to 3)
2. : Setting is fixed in the UART reception mode, : 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
