60 / 92 page  AMC7812 SBAS513E – JANUARY 2011 – REVISED SEPTEMBER 2013 www.ti.com REGISTERS REGISTER MAP The AMC7812 has several 16-bit registers that consist of a high byte (8 MSBs) and a low byte (8 LSBs). An 8-bit register pointer points to the proper register. The pointer does not change after the operation. Table 10 lists the registers for the AMC7812. Note that the default values are for SPI operation; see the register descriptions for I2C default values. Table 10.
