General purpose input/output. It has the same behavior as CRDIO. It can be connected to the
C8 pin of the card connector.
This pin is the return path for the current flowing into Pin 22 (L1). It must be connected to
CRDGND using appropriate grounding techniques.
This pin is the signal ground. It must be connected to the ground pin of the card connector. It is
the reference level for all analog and digital signals.
This pin connects to the V
Pins 11, 14, 15, 16 and 19.
This pin connects to an external inductance for the DC−DC converter. Please refer to the
description of the DC−DC converter functional block.
This pin is connected to the supply voltage. Logic level “1” of Pins 2 to 10, 17, 18, 20 and 21 is
referenced to V
minimum value.
This pin can be connected to the PGND pin, or to a resistor connected to PGND, or left open,
depending on the peak coil current needed to supply the card.
