[1:0] Page mode configuration (PMC)
00 = Normal ROM
10 = 8-word page
[3:2] Page address access time (t
00 = 5 cycles
10 = 3 cycles
[6:4] Programmable access cycle (t
000 = Disable bank
010 = 3 cycle
110 = 7 cycle
[19:10] ROM/SRAM/Flash bank # base pointer
This value is the start address of the ROM/SRAM/Flash bank #.
The start address is calculated as ROM/SRAM/FLASH bank #
base pointer << 16.
[29:20] ROM/SRAM/FLASH bank # next pointer
This value is the current bank end address << 16 + 1.
