The power up sequence for the AMC7891 states: "Supply all voltages (AVDD, GPIOVDD and SPIVDD). If possible, it is recommended to apply IOVDD before AVDD. However, the supplies can be powered up simultaneously or in any order with no detrimental effect to the device."
Our current power up sequence has AVdd coming up before GPIOVdd and SPIVdd which according to the directions, is not recommended, but will have no detrimental effect. Why is it not recommended and is there anything I need to watch out for?
Thanks,
