Product overview STM8AF52/62xx, STM8AF51/61xx
24/110 Doc ID 14395 Rev 9
Detailed feature list:
● Full duplex, asynchronous communications
● NRZ standard format (mark/space)
● High-precision baud rate generator system
– Common programmable transmit and receive baud rates up to f
MASTER
/16
● Programmable data word length (8 or 9 bits)
● Configurable stop bits: Support for 1 or 2 stop bits
● LIN master mode:
– LIN break and delimiter generation
– LIN break and delimiter detection with separate flag and interrupt source for
readback checking.
● Transmitter clock output for synchronous communication
● Separate enable bits for transmitter and receiver
● Transfer detection flags:
– Receive buffer full
– Transmit buffer empty
– End of transmission flags
● Parity control:
– Transmits parity bit
– Checks parity of received data byte
● Four error detection flags:
– Overrun error
– Noise error
–Frame error
– Parity error
● Six interrupt sources with flags:
– Transmit data register empty
– Transmission complete
– Receive data register full
– Idle line received
– Parity error
– LIN break and delimiter detection
● Two interrupt vectors:
– Transmitter interrupt
– Receiver interrupt
● Reduced power consumption mode
● Wakeup from mute mode (by idle line detection or address mark detection)
● Two receiver wakeup modes:
– Address bit (MSB)
– Idle line
