Serial channels

Serial communication with other microcontrollers, microprocessors, terminals or external

peripheral components is provided by two serial interfaces: the asynchronous / synchronous

serial channel (ASCO) and the high-speed synchronous serial channel (SSC). Two

dedicated Baud rate generators set up all standard Baud rates without the requirement of

oscillator tuning. For transmission, reception and erroneous reception, 3 separate interrupt

vectors are provided for each serial channel.

14.1

Asynchronous / Synchronous Serial Interface (ASCO)

The asynchronous / synchronous serial interface (ASCO) provides serial communication

between the ST10F280 and other microcontrollers, microprocessors or external peripherals.

A set of registers is used to configure and to control the ASCO serial interface:

●

P3, DP3, ODP3 for pin configuration

●

SOBG for Baud rate generator

●

SOTBUF for transmit buffer

●

SOTIC for transmit interrupt control

●

SOTBIC for transmit buffer interrupt control

●

SOCON for control

●

SORBUF for receive buffer (read only)

●

SORIC for receive interrupt control

●

SOEIC for error interrupt control
