Description
control with CLKDIV2 for choosing CLK frequency
control with CLKDIV1 for choosing CLK frequency
reserved for future use (to be connected to V
microcontroller I/O; active HIGH)
power ground for step-up converter
capacitance connection for step-up converter (a 100 nF
capacitor with ESR < 100 m must be connected between
pins S1 and S2)
power supply voltage for step-up converter
capacitance connection for step-up converter (a 100 nF
capacitor with ESR < 100 m must be connected between
pins S1 and S2)
output of step-up converter (a 100 nF capacitor with
ESR < 100 m must be connected to PGND)
card presence contact input (active LOW); if PRES or PRES
is true, then the card is considered as present
