SPI CLK
SPI data to 6208
SPI Enable
RESET to be held low until
SPI operations are complete
Microcontroller can be programmed to load device registers
at power up. RESETN is help low during SPI operations.
When register loading is complete, RESETN is set high and
MSP430 enters low-power mode. MSP430 supply needs to be at
least 1.8V for proper operation.
Optional Inputs for MSP430 Firmware
Use to select between different register preload options.
