PCMCIA Interface
The calculated bank size is used as a mask (MASK) to determine a valid PCMCIA address
as follows:
00101 = 64 bytes.
00100 = 128 bytes.
01100 = 256 bytes.
01101 = 512 bytes.
01111 = 1K.
01110 = 2K.
01010 = 4K.
01011 = 8K.
01001 = 16K.
01000 = 32K.
11000 = 64K.
11001 = 128K.
11011 = 256K.
11010 = 512K.
11110 = 1M.
11111 = 2M.
11101 = 4M.
11100 = 8M.
10100 = 16M.
10101 = 32M.
10111 = 64M.
If ((Address & MASK) == (PBA & MASK))
else
