(2) Note the NAND flash area setting
Figure 3.8.8 shows a memory map for NAND flash.
And since CS3 area is recommended to assign address from 000000H to 3FFFFFH, this
case is explained.
In this case, “NAND flash” and CS3 area are overlapped. But 3 CS pin don’t become
active by setting BROMCR to “1”. And also 0 CS to 3 CS , SDCS , CSXA to CSXB ,
CSZA to CSZD pins don’t become to active.
Note1: In this case, the address from 000000H to 049FFFH of 296 Kbytes in CS3’s memory can’t be used.
Note2: 16 byte area (001FF0H to 001FFFH) for NAND Flash are fixed like a following without relationship to
setting CS bock. Therefore, NAND flash area don’t according to CS3 area setting.
(NAND-Flash area specification)
1. bus width : Depend on NDFMCR1 in NAND Flash controller.
2.WAIT control : Depend on NDFMCR, in NAND Flash controller
