stored in SC0CR<RB8>. For writing and reading of the buffer, the MSB is read or
written first then the rest of the data from SC0BUF.
Wakeup function
Note:
9-bit UART mode can be specified by setting SC0MOD<SM1:0> to 11. In this mode,
For transmission, the MSB (9th bit) is written in SC0MOD<TB8>. For receiving it is

setting SC0MOD<WU> to 1. The interrupt INTRX0 occurs only when<RB8> = 1.
Master
In 9-bit UART mode, the wakeup function of slave controllers is enabled by
← − − − 0 − − − −
← − 0 1 X 1 0 0 1
← X 0 1 X X X 0 0
← 0 0 0 1 0 1 0 1
← 1 X − − − − − −
← − − − − 1 1 0 0
← SC0CR AND 00011100
← SC0BUF
TXD pin of the slave controllers must be in open-drain output mode.
