I2C-BUS AND 3-WIRE INTERFACES
Register denitions
The configuration of the different registers is shown in Table 1.
Table 1
I2C-bus and 3-wire registers
All the registers are defined by a subaddress of 8 bits; bit A4 refers to the mode which is used with the I2C-bus interface; bits Sa3 to Sa0 are the
subaddresses of each register.
The bit mode, used only with the I2C-bus, enables two modes to be programmed:
If Mode = 0, each register is programmed independently by giving its subaddress and its content
If Mode = 1, all the registers are programmed one after the other by giving this initial condition (xxx1 1111) as the subaddress state; thus, the registers
are charged following the predefined sequence of 16 bytes (from subaddress 0000 to 1101).
