Page 34: Test Modes
Evalkit for Pressure Sensors KP12x Kit Digital Interface for EEPROM access Test Modes Test mode must be activated by writing “2CEh” to the status register (Addr. 08h). Any other sequence written to the status register disables the test mode and brings the chip back to normal operation. The cyclic EEPROM refresh and the FEC ERR / ACT flag calculation is deactivated in test mode, therefore refresh and calc FEC has to be triggered manually. -
