Note: 1. If no input (IO1, IO2, AUX1, AUX2) is selected for a SCIB pin (CIOn, CC4n CC8n), and if the
smart card interface is started, the electrical level on the SCIB pin corresponds to the CAR-
DIOn, CARDC4n or CARDC8n bit value.
2. For IOSEL[3:0] = 0xOE and IOSEL[3:0] = 0x0F, the CARDRST3 bit must be set to connect
AUX2 to CRST3/CC82 pin.
