External Signal Description

The IICV2 module has two external pins.

9.2.1

IIC_SCL — Serial Clock Line Pin

This is the bidirectional serial clock line (SCL) of the module, compatible to the IIC bus speciﬁcation.

9.2.2

IIC_SDA — Serial Data Line Pin

This is the bidirectional serial data line (SDA) of the module, compatible to the IIC bus speciﬁcation.

9.3

Memory Map and Register Deﬁnition

This section provides a detailed description of all memory and registers for the IIC module.

9.3.1

Module Memory Map

The memory map for the IIC module is given below in Table 1-1. 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.
