5.3.2 Digital I/O level shifter
All the CMA3000 products have an internal level shifter that can be used to interface e.g. a micro
controller using lower supply than the CMA3000. The level shifter is "programmed" by providing the
supply voltage of the interfaced device to the DVIO-pin. Please refer to the corresponding product
data sheet for details.
