Function Description
Serial interfaces I
2
C bus
interface 2
(IIC2)
• One channel (SSU and selection format)
• Continuous transmission and reception possible
• Two transmission/reception formats
⎯ I
2
C bus format: generates start and stop conditions in
master mode automatically, acknowledge bit, master or
slave operation
⎯ Clock-synchronous serial format: no acknowledge bit,
master operation only
Hardware
LIN interface
One channel (timer RA and SCI3 used)
Event link controller (ELC) Events (interrupts) generated by peripheral modules can be
interconnected between modules, enabling cooperation between
the modules without CPU intervention.
