Serial port interface system and method for an analog-to-digital converter

摘要: A novel serial port interface system and method are disclosed. The achieves a three-pin mode with only data input pin, output clock pin by allocating bit in an on-chip register to identify conversion-done mode. In this mode, the signals external device that is ready be accessed. Also disclosed single conversion read continuous may selected through two separate bits register. another aspect, multiple access capability allows registers accessed read/write command. This accomplished select address command group of registers, such as all set-up (gain, offset configuration). An invalid lock also places hold state, if decoded, protect from corruption. Control removed until specific restart sequence applied.
