2.5.1
The TC1797 includes two Asynchronous/Synchronous Serial Interfaces, ASC0 and
ASC1. Both ASC modules have the same functionality.

The ASC provides serial communication between the TC1797 and other
microcontrollers, microprocessors, or external peripherals.
The ASC supports full-duplex asynchronous communication and half-duplex
synchronous communication. In Synchronous Mode, data is transmitted or received
synchronous to a shift clock that is generated by the ASC internally. In Asynchronous
Mode, 8-bit or 9-bit data transfer, parity generation, and the number of stop bits can be
selected. Parity, framing, and overrun error detection are provided to increase the
reliability of data transfers. Transmission and reception of data is double-buffered. For
multiprocessor communication, a mechanism is included to distinguish address bytes
from data bytes. Testing is supported by a loop-back option. A 13-bit baud rate generator
provides the ASC with a separate serial clock signal, which can be accurately adjusted
by a prescaler implemented as fractional divider.
