Serial Frames
Frame Formats
The EUSART supports more serial frame formats than the standard USART interface:
A serial frame is defined to be one character of data bits with synchronization bits (start and stop
bits), and optionally a parity bit for error checking.
The EUSART allows to receive and transmit serial frame with the following format:
• Asynchonous frames
• Synchronous frames
• 1 start bit
• 5, 6, 7, 8, 9, 13, 14,15,16,17 data bits
• data bits and start bit level encoded or Manchester encoded
• data transmition MSB or LSB first (bit ordering)
• no, even or odd parity bit
• 1 or 2 stop bits:
– Standard bit level encoded
– Manchester bit encoded
– In this mode only the Standard bit level encoded is available
