Refer to the register descriptions in
definitions of each bit.
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 an entire frame of “1”s followed by the start bit of the next
frame which contains data.
A break character is interpreted on receiving “0”s for some multiple of the frame period. At
the end of the last break frame the transmitter inserts an extra “1” bit to acknowledge the
start bit.
Transmission and reception are driven by their own baud rate generator.
Figure 89. Word length programming
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.
When the transmit enable bit (TE) is set, the data in the transmit shift register is output on
the TDO pin and the corresponding clock pulses are output on the SCLK pin.
