Number of channels: Two (max.)
Supports transfer of compressed and non-compressed data
Selectable frame size
Number of channels: One (max.)
Exclusively for NAND-type flash memory
Operating modes: Command-access mode, sector-access mode
Data transfer FIFOs
⎯ On-chip 224-byte FIFO for transfer of data to and from flash memory
⎯ On-chip 32-byte FIFO for transfer of control codes
⎯ Flag bit to indicate overruns and underruns during access from the
