redundant area is pushed by uC and popped by MHE when SmartMedia MIF is
enabled.
3.2.5.3 Buffer Mode:
1. Buffer mode is enabled by firmware and is used to copy data block from source
to destination in same card for SmartMedia or MemoryStick applications.
2. Under Buffer mode, firmware can enable MIF to read source data block to
TXFIFO, check the data integrity, then enable MIF to write data in TXFIFO to
destination data block space on memory card.
3.
For SmartMedia application, the redundant data write to destination data block
space is from redundant area of RXFIFO.
