Function
Multi-page DMA size bit. Maximum 15 pages are accessible at a time.
0000 = not defined.
0001 = 1 page
0010 = 2 pages
…
1111 = 15 pages
Wait counter maximum limit value. Waiting time delay between address latch and write data in
page program mode or between address latch and read data in read ID mode and read status
register is determined by this register.
0000 = 1 BCLK width
0001 = 2 BCLK width
…
1111 = 16 BCLK width
Reserved
Should set these bits as 0x7F to access full 512 bytes page at one access command (read or
program).
Reserved
High pulse width value of read enable and write enable signal. The width must satisfy the AC
characteristics of SmartMedia to guarantee correct transfer of data. With Safety Margin
enable, width will be decreased by one.
00 = 1 BCLK width (0 BCLK with safety margin enable. Don’t make this case)
01 = 2 BCLK width (1 BCLK with safety margin enable)
10 = 3 BCLK width (2 BCLK with safety margin enable)
11 = 4 BCLK width (3 BCLK with safety margin enable)
Reserved
Low pulse width value of read enable and write enable signal. The width must satisfy the AC
characteristics of SmartMedia to guarantee correct transfer of data. With Safety Margin
enable, width will be decreased by one.
000 = 1 BCLK width (0 BCLK with safety margin enable, Don’t make this case)
001 = 2 BCLK width (1 BCLK with safety margin enable)
…
111 = 8 BCLK width (7 BCLK with safety margin enable)
