ASC supports full-duplex asynchronous communication up to 2.25 MBaud and half-
duplex synchronous communication up to 4.5 MBaud (@ 36 MHz CPU clock which is
equal to the ASC module clock). In synchronous mode, data are transmitted or received
synchronous to a shift clock which is generated by the microcontroller. In asynchronous
mode, 8- or 9-bit data transfer, parity generation, and the number of stop bits can be
selected. Parity, framing, and overrun error detection is provided to increase the
reliability of data transfers. Transmission and reception of data is double-buffered. For
multiprocessor communication, a mechanism to distinguish address from data bytes is
included. Testing is supported by a loop-back option. A 13-bit baudrate timer with a
versatile input clock divider circuitry provides the ASC with the serial clock signal. In a
special asynchronous mode, the ASC supports IrDA data transmission up to 115.2
kBaud with fixed or programmable IrDA pulse width. A autobaud detection unit allows to
detect asynchronous data frames with its baudrate and mode with automatic initialization
of the baudrate generator and the mode controll bits.
A transmission is started by writing to the Transmit Buffer register S0TBUF. Only the
number of data bits which is determined by the selected operating mode will actually be
transmitted, ie. bits written to positions 9 through 15 of register S0TBUF are always
insignificant.
