These phases are generated through a sequence of writes
to 1Ch. In certain action, the driver must wait until the
minimum timing requirement for the serial ROM opera-
tion is met in order to advance to the next action. A
typical driver sequence can look like this
Write register 1Ch 00H ( >= 30ns )
Write register 1Ch 01H ( >= 50ns )
Write register 1Ch 03H ( >= 250ns )
Write register 1Ch 01H ( >= 100ns )
Write register 1Ch 05H ( >= 150ns )
Write register 1Ch 07H ( >= 250ns )
Write register 1Ch 05H ( >= 100ns )
Write register 1Ch 01H ( >= 150ns )
Write register 1Ch 03H ( >= 250 ns )
Write register 1Ch 01H ( >= 100 ns )
Write register 1Ch 05H ( >= 150 ns )
Write register 1Ch 07H ( >= 250 ns )
Write register 1Ch 05H ( >= 100ns )
Write register 1Ch 00H ( >= 150 ns )
Write register 1Ch 00H ( >= 250 ns )
Write register 1Ch 00H ( >= 100ns )
Write register 1Ch 03H ( >= 150ns )
Write register 1Ch 0XH ( >= 250ns )
Write register 1Ch 0XH ( >= 100ns )
Write register 1Ch 00H ( >= 250ns )
Write register 1Ch 01H ( >= 250ns )
*Read register 1Ch.3
if register 1Ch.3 = 1 then go on
Write register 1Ch 00H ( >= 250ns )
else
Wait 1 ms then go to *Read register 1Ch.3
