Asynchronous/Synchronous Serial Interfaces (ASC 0/1/2)
The Asynchronous/Synchronous Serial Interface ASC provides serial communication
between the TriCore and other microcontrollers, microprocessors or external
peripherals. The implementation is held parametrizable in order to allow the usage of
parallel busses of different width and with different protocols.
Features:
• Full duplex asynchronous operating modes
– 8- or 9-bit data frames, LSB first
– Parity bit generation/checking
– One or two stop bits
– Baudrate from 3.125 MBaud to 0.74 Baud (@ 50 MHz module clock)
– Multiprocessor mode for automatic address/data byte detection
– Loop-back capability
• Half-duplex 8-bit synchronous operating mode
– Baudrate from 6.25 MBaud to 637 Baud (@ 50 MHz module clock)
• Double buffered transmitter/receiver
• Interrupt generation
– on a transmitter buffer empty condition
– on a transmit last bit of a frame condition
– on a receiver buffer full condition
– on an error condition (frame, parity, overrun error)
• Support for IrDA
• Automatic Baudrate Detection
• 8 Byte FIFO
