PNEV5190B evaluation board quick start guide
•
Read EEPROM
Reads a single byte from EEPROM using byte address
•
Write EEPROM
Writes a single byte into EEPROM using byte address
•
Dump EEPROM
Stores the complete user area of the PN5190 EEPROM into an XML file. This can be
used to generate a backup of all settings or to transfer optimized settings onto another
board or into own software. It makes sense to save all default EEPROM settings into a
file, before modifying the EEPROM.
•
Load EEPROM
Loads an XML file and stores the content into the user area of the PN5190 EEPROM.
The format is fixed and must fit.
1. EEPROM means User area of the EEPROM

5.2.3 PN5190 analog and digital test signals
The NFC cockpit allows using the PN5190 internal test bus, to route the digital and
analog test signals to the given test pins. Details can be found in the CTS description.
The test pins can be found at TB0, TB1 and TB2.
5.2.4 PN5190 dynamic power control
The NFC Cockpit supports an easy and straight forward calibration of the DPC. All details
can be found in
