microSD card slot
Secure Digital (SD) is a non-volatile
memory card format developed for use
in portable devices. It comes in different
packages and memory capacities. It is
mostly used for storing large amounts
of data. EasyPIC Fusion
microSD card slot. The microSD form
factor is the smallest card format currently
available. It uses standard SPI user inter-
face with minimum additional electronics,
mainly used for stabilizing communication
lines which can be significantly distorted
at high transfer rates. Special ferrite is
also provided to compensate the voltage
and current glitch that can occur when
pushing-in and pushing-out microSD card
into the socket.

In order to access microSD card, you
must enable SPI communication
lines using SW13.1 – SW13.3 DIP
switches as well as Chip Select (CS)
and Card Detect (CD) lines using
SW14.1 and SW14.2 switches.
