The Asynchronous/Synchronous Serial Interfaces ASC0/ASC1 (USARTs) provide serial
communication with other microcontrollers, processors, terminals or external peripheral
components. They are upward compatible with the serial ports of the Infineon 8-bit
microcontroller families and support full-duplex asynchronous communication and half-
duplex synchronous communication. A dedicated baud rate generator with a fractional
divider precisely generates all standard baud rates without oscillator tuning. For
transmission, reception, error handling, and baudrate detection 5 separate interrupt
vectors are provided.
In asynchronous mode, 8- or 9-bit data frames (with optional parity bit) are transmitted
or received, preceded by a start bit and terminated by one or two stop bits. For
multiprocessor communication, a mechanism to distinguish address from data bytes has
been included (8-bit data plus wake-up bit mode). IrDA data transmissions up to
115.2 kbit/s with fixed or programmable IrDA pulse width are supported.
In synchronous mode, bytes (8 bits) are transmitted or received synchronously to a shift
clock which is generated by the ASC0/1. The LSB is always shifted first.
In both modes, transmission and reception of data is FIFO-buffered. An autobaud
detection unit allows to detect asynchronous data frames with its baudrate and mode
with automatic initialization of the baudrate generator and the mode control bits.
A number of optional hardware error detection capabilities has been included to increase
the reliability of data transfers. A parity bit can automatically be generated on
transmission or be checked on reception. Framing error detection allows to recognize
data frames with missing stop bits. An overrun error will be generated, if the last
character received has not been read out of the receive buffer register at the time the
reception of a new character is complete.
