The peripheral functions used in the LIN communication operation are shown below.
<Peripheral functions used>
 External interrupt (INTP0); wakeup signal detection
Use: Detects the wakeup signal edges and detects start of communication.
 16-bit timer/event counter 00 (TI000); baud rate error detection
Use: Detects the baud rate error (measures the TI000 input edge interval in the capture mode) by detecting the
sync field (SF) length and divides it by the number of bits.
 Serial interface UART6
(3) DALI mode
This mode is used to perform slave transmission/reception of DALI (Digital Addressable Lighting Interface).
See 14.4.3 DALI mode for details.
Remark DALI is an international open standard lighting control communication protocol, mainly used for light control
of multiple fluorescent lamps or LED lights.
DALI is a network consisting of up to 64 short addresses and 16 group addresses, and performs half-
duplex command communication between one master and one slave or multiple slaves.
DALI commands are used for purposes such as setting the light control level with 8-bit accuracy and saving
or switching among up to 16 arbitrary light control levels.
The communication speed is 1,200 Hz 10%.
