14.2.1 Data Format
The serial data format requires these conditions:
A frame consists of:
A BREAK is defined as the transmission or reception of a logic 0 for one frame or more.
This SCI supports hardware parity for transmit and receive.
14.2.2 SCI Baud Rate Generation
The basis of the SCI baud rate generator is a 13-bit modulus counter. This counter gives the generator
the flexibility necessary to achieve a reasonable level of independence from the CPU operating frequency
and still be able to produce standard baud rates with a minimal amount of error. The clock source for the
generator comes from the P clock.
Freescale Semiconductor
An idle-line in the high state before transmission or reception of a message
A start bit (logic 0), transmitted or received, that indicates the start of each character
Data that is transmitted or received least significant bit (LSB) first
A stop bit (logic 1) used to indicate the end of a frame
A start bit
A character of eight or nine data bits
A stop bit
