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
I
