STM8S207xx, STM8S208xx Product overview
Doc ID 14733 Rev 12 21/103
Asynchronous communication (UART mode)
● Full duplex communication - NRZ standard format (mark/space)
● Programmable transmit and receive baud rates up to 1 Mbit/s (f
CPU
/16) and capable of
following any standard baud rate regardless of the input frequency
● Separate enable bits for transmitter and receiver
● Two receiver wakeup modes:
– Address bit (MSB)
– Idle line (interrupt)
● Transmission error detection with interrupt generation
● Parity control
LIN master capability
● Emission: Generates 13-bit synch break frame
● Reception: Detects 11-bit break frame
LIN slave mode
● Autonomous header handling - one single interrupt per valid message header
● Automatic baud rate synchronization - maximum tolerated initial clock deviation ±15 %
● Synch delimiter checking
● 11-bit LIN synch break detection - break detection always active
● Parity check on the LIN identifier field
● LIN error management
● Hot plugging support
4.14.3 SPI
● Maximum speed: 10 Mbit/s (f
MASTER
/2) both for master and slave
● Full duplex synchronous transfers
● Simplex synchronous transfers on two lines with a possible bidirectional data line
● Master or slave operation - selectable by hardware or software
● CRC calculation
● 1 byte Tx and Rx buffer
● Slave/master selection input pin
