15.1
The ASC supports full-duplex asynchronous communication up to 1.5 MBaud and half-
duplex synchronous communication up to 3 MBaud (@ 24 MHz CPU clock) . In synchro-
nous mode, data are transmitted or received synchronous to a shift clock which is gen-
erated by CPU. In asynchronous mode, 8- or 9-bit data transfer, parity generation, and
the number of stop bits can be selected.
15.1.1
Full duplex asynchronous operating modes
• 8- or 9-bit data frames, LSB first
• Parity bit generation/checking
• One or two stop bits
• Baudrate from 1.5 MBaud to 0.3552 Baud (@24 MHz CPU clock)
• Multiprocessor mode for automatic address/data byte detection
• Loop-back capability
• Support for IrDA data transmission/reception up to max 115.2 KBaud
Half-duplex 8-bit synchronous operating mode
• Baudrate from 3 MBaud to 305.76 Baud (@ 24 MHz CPU 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)
