It is clocked by the internal LSI RC clock source, and thus stays active even in case of a
CPU clock failure.
Beeper
The beeper function outputs a signal on the BEEP pin for sound generation. The signal is in
the range of 1, 2 or 4 kHz.
Communication interfaces
SPI
The serial peripheral interfaces (SPI1 and SPI2) provide half/ full duplex synchronous serial
communication with external devices.
