Set DMAC related registers (example of channel 0, 1)
1. DMA source address registers (SAR0, SAR1)
2. DMA destination address registers (DAR0, DAR1)
3. DMA transfer count registers (TCR0, TCR1)
4. DMA channel control registers (CHCR0, CHCR1)
5. DMA extended resource selector (DMARS0)
Set DMA operation register (DMAOR0)
DME = 1 (enable channel 0 to 5 transfer)
Set common control register (FLCMNCR)
ACM [1:0] = 01 (sector access mode)
CE0 = 1 (chip enable)
TYPESEL = 1 (NAND flash memory)
Specify ECC position to ECCPOS [1:0]
Set command control register (FLCMDCR)
SELRW = 1 (flash write)
DOCMD1 = 1 (perform first command stage)
DOCMD2 = 1 (perform second command stage)
DOADR = 1 (perform address stage)
ADRMD = 1 (specify sector access address)
ADRCNT [1:0] = 10 (issue 3-byte address)
DOSR = 1 (perform status read)
Specify number of sector transfer to SCTCNT [15:0]
Set command code register (FLCMCDR)
CMD [7:0] = H'80 (flash write command)
CMD [15:8] = H'10 (flash write execute command)
SAR0 [31:0]: set start address of writing data
SAR1 [31:0]: set start address of writing control code
DAR0 [31:0]: set FLDTFIFO address
DAR1 [31:0]: set FLECFIFO address
TCR0 [31:0] = H'0000 0080 (512 bytes = 4 x 128)
TCR1 [31:0] = H'0000 0004 (16 bytes = 4 x 4)
SM [1:0] = 01 (source address is incremented)
RS [3:0] = 1000 (on-chip peripheral module request)
TS [2:0] = 010 (longword)
DE = 1 (DMA transfer enable)
DMARS0 [15:0] = H'8783 (FLCTL control code and
data part transmit and receive)
