What happens if the ST25R3911B RFI1 and RFI2 input signal peak values exceed the Vsp_a supply voltage level?
Reference is to ST25R3911B data sheet, page 16, section 1.2.3
Concern is is the SS25R3911B damaged or just fails to operate properly?

Hi,
please see p.121, symbol VRFI_A. Max 3V. Everything above is outside of the electrical limits and potentially damages the chip.
