USER’S MANUAL
All data frames must have a start bit and at least one stop bit. Receiving and transmit-
ting devices must use the same data frame format. The SCI provides hardware sup-
port for both 10-bit and 11-bit frames. The M bit in SCCxR1 specifies the number of
bits per frame.
The most common data frame format for NRZ (non-return to zero) serial interfaces is
one start bit, eight data bits (LSB first), and one stop bit (ten bits total). The most com-
mon 11-bit data frame contains one start bit, eight data bits, a parity or control bit, and
one stop bit. Ten-bit and 11-bit frames are shown in
The SCI baud rate is programmed by writing a 13-bit value to the SCxBR field in SCI
control register zero (SCCxR0). The baud rate is derived from the MCU IMB clock by
a modulus counter. Writing a value of zero to SCxBR[12:0] disables the baud rate gen-
erator. The baud rate is calculated as follows:
where SCxBR is in the range {1, 2, 3, ..., 8191}.
• Break frame — A frame that consists of consecutive zeros. A break frame has no
/
stop bits.
