Chapter 15 Inter-Integrated Circuit (IICV3) Block Description
15.1.2
The IIC functions the same in normal, special, and emulation modes. It has two low power modes: wait
and stop modes.
15.1.3
The block diagram of the IIC module is shown in
15.2
The IICV3 module has two external pins.
15.2.1
This is the bidirectional serial clock line (SCL) of the module, compatible to the IIC bus specification.
15.2.2
This is the bidirectional serial data line (SDA) of the module, compatible to the IIC bus specification.
