base function offset description contents/example
0x0D010000 NAND
0000 W command 9F000000 (CMD 00: start read sector)
8030B840 (CMD 30: data (starts DMA 0x840 bytes))
80FF8000 (CMD FF: reset)
00008000 means: wait for R/#B to go down
1F000000 is the mask of the address bytes to send. (10 = AA, 08 = BB, .., 01 = FF in 08,0c)
0000 R status MSB means busy
0004 W config
0008 W address #0 0000AABB
000C W address #1 CCDDEEFF, NAND sector, multiply with 0x800 or 0x840 to get offset, 0x40 for ecc
0010 W data addr target address for DMA (0x800 main bytes)
0014 W ecc addr target address for DMA (0x40 spare bytes + 0x10 byte HW-calculated ECC syndrome)
0018 W unknown
