Hi,
We use the ADAU1445 audio processor for intercom - and audio purposes in a video camera system. At startup of the system we load the processor software via the I2C connection. For test purposes in the factory we use the selfboot option to load the testsoftware from an on board EEPROM. We use in the test bench the GPIO inputs to control some functions in the processor. In this way it is not necessary to relocate control register addresses after a change in the processor test software. However I need more GPIO's to control all the test functions. Are there logic operators available for the GPIO inputs in order I can create 2^n functions with n GPIO inputs?
With kind regards,
Gerard van Beijsterveld
