ST25R3916B + RFAL does not specify/clear an interrupt after Measure Power Supply command
I'm working on porting the RFAL for ST25R3916B to an nRF5340, using the pairing example for X-NUCLEO-8. I have it all compiling and flashing correctly, but things break down during initialization here:
In rfalInitialize() -> st25r3916Initialize(), the issue occurs when trying to measure voltage with st25r3916MeasureVoltage(). After executing st25r3916ExecuteCommandAndGetResult, I get the below SPI trace. The IRQ line goes high as expected, the RFAL then sends a read request for registers 0x1A through 0x1D, and the ST25R3916B does not respond with any active IRQs and does not clear the IRQ line. This results in a memory access violation on the nRF5340.
This is the standard, unmodified RFAL for ST25R3916/B. The DCT interrupt is enabled. The SPI trace looks exactly the same as a previous IRQ read. Is there something different about the Measure Power Supply (0xDF) command? Any help would be appreciated.
