Bits 14 and 13 are also set to “0” when thelower byte of the UARTi receive buffer register (addresses 03A616, 03AE16 and 037E16) is read out.Note 2: Arbitration lost detecting flag is allocated to U2RB and noting but “0” may be written. Nothing isassigned in bit 11 of U0RB and U1RB. These bits can neither be set or reset.
