the user may reset the data controller and its internal state machine by setting and clearing the
DCR bit in MMCON2 register.
This time-out may be disarmed after receiving 8 data (F1FI flag set) or after receiving end of
frame (EOFI flag set) in case of block length less than 8 data (1, 2 or 4).
Data is read from the FIFO by reading to MMDAT register. Each time one FIFO becomes full
(F1FI or F2FI set), user is requested to flush this FIFO by reading 8 data.
