This might be convenient if the user wants to use NFC Cockpit on their device.
See the photo of PNEV5190BP EVK with the instructions.
1. Place R5 and R7, keep R6 open
2. Place R20, keep R19 open
Note: This step depends on the voltage domain used in the external hardware. If R19 is placed -> 1.8V domain, if R20 is placed -> 3.3V domain.
3. Remove VBAT, VBAT_PWR, and VUP jumpers to disconnect the "internal" PN5190 located on the EVK
4. Connect the following SPI lines to external PN5190 (e.g., customer HW)
- SPI_CLK
- SPI_MOSI
- SPI_MISO
- SPI_CS
- NFC_IRQ
- GND
Note: It is also necessary to disconnect the external PN5190 from the customer MCU.
5. Connect VEN to the external PN5190
Now, the external PN5190 HW should communitate with the MCU located in PNEV5190BP, and the NFC Cockpit can be used. The user should see that the blue LED is on. If the red LED is blinking, there is an issue, and the user should check the connections/supply.
