MCP6S21/2/6/8 5.0 DIGITAL FUNCTIONS The MCP6S21/2/6/8 PGAs use a standard SPI com- patible serial interface to receive instructions from a controller. This interface is configured to allow daisy chaining with other SPI devices. There is an internal POR (Power On ...
Page 19
Registers The analog functions are programmed through the SPI interface using 16-bit words (see Figure 5-1 and Figure 5-2). This data is sent to two of three 8-bit regis- ters: Instruction Register (Register 5-1), Gain Register (Register 5-2) and ...
