The PDC interface block controls all data routing between the external data bus, internal
MMC/SD module data bus, and internal system FIFO access through a dedicated state machine
that monitors the status of FIFO content (empty or full), FIFO address, and byte/block counters
for the MMC/SD module (inner system) and the application (user programming).
These timings are given for a 25 pF load, corresponding to 1 MMC/SD Card.
