Selecting a register reads and shows the hexadecimal content as well as the
corresponding bit values. The input allows to change each bit separately as well as
writing hexadecimal values. Writing back the value changes the PN5180 register.
A help function automatically shows a brief description of the (part of the) registers itself,
if the mouse is moved over the names.
Note: Some register content cannot be changed manually (“read only”) and some
content might be overwritten by the PN5180 firmware.
1. Register area is a RAM area, i.e. might be overwritten or changed automatically.

4.3 PN5180 EEPROM access
The NFC Cockpit allows different options of EEPROM access (see Fig 19):
EEPROM area for RF_CONFIG
All registers, which are used in the LOAD_RF_CONFIG command, can be read directly
from the EEPROM: The user must select the “register” and the protocol.
All registers, which are used in the LOAD_RF_CONFIG command, can be directly written
into the EEPROM. The user must select the “register” and the protocol.
This allows an easy EEPROM update of the relevant TX and Rx registers after
optimization in RAM.
EEPROM area 0x00 … 0xFC
• Read EEPROM
Reads a single byte from EEPROM using byte address from 0x00 to 0xFC
• Write EEPROM
