Serial data format
Word length may be selected as being either 8 or 9 bits by programming the M bit in the
SCICR1 register (see
The TDO pin is in low state during the start bit.
The TDO pin is in high state during the stop bit.
An idle character is interpreted as a continuous logic high level for 10 (or 11) full bit times.
A break character is a character with a sufficient number of low level bits to break the normal
data format followed by an extra “1” bit to acknowledge the start bit.

Transmitter
The transmitter can send data words of either 8 or 9 bits depending on the M bit status.
When the M bit is set, word length is 9 bits and the 9th bit (the MSB) has to be stored in the
T8 bit in the SCICR1 register.
An extended prescaler receiver register (SCIERPR)
