Diagnostic and Therapy Devices Data can be sent as 8- or 9-bit words, least significant bit (LSB). A START bit marks the beginning of the frame, and is active low. Figure 14-8 shows a framed 8-bit data word. The data word follows the start bit. A parity bit may follow the data word after the most significant bit (MSB) depending on the protocol used. A mark parity bit (always set high), a space parity bit (always set low) or an even/odd parity bit may be used. The even parity bit will be a one if the number of ones/zeros is even or a zero if there is an odd number. The odd parity bit will be high if there are an odd number of ones/zeros in the data field. A stop bit will normally follow the data field. The stop bit is used to bring the signal rests at logic high following the end of the frame, so when the next start bit arrives it will bring the bus from high to low. Idle characters are sent as all ones with no start or stop bits. Freescale MCUs provide 13-bit baud. The SCI modules can operate in low-power modes. Ethernet PHY (100 Mbps) To connect the MCU to the Internet or to control the system remotely, you can implement an Ethernet communication interface. This needs coupling impedance for the RJ-45 connection. 15.6 Backlight Inverter A backlight is a form of illumination used in liquid crystal displays (LCDs). Backlights illuminate the LCD from the side or back of the display panel, unlike front lights, which are placed in front of the LCD.
