Chapter 11 Inter-Integrated Circuit (IICV2)
11.2.1 IIC_SCL — Serial Clock Line Pin
This is the bidirectional serial clock line (SCL) of the module, compatible to the IIC bus specification.
11.2.2 IIC_SDA — Serial Data Line Pin
This is the bidirectional serial data line (SDA) of the module, compatible to the IIC bus specification.
11.3 Memory Map and Register Definition
This section provides a detailed description of all memory and registers for the IIC module.
11.3.1 Module Memory Map
The memory map for the IIC module is given below in Table 11-1. The address listed for each register is
the address offset.The total address for each register is the sum of the base address for the IIC module and
the address offset for each register.
