Notes 1.
This applies when the main clock division selection bit = “0” and f(f
2
) = 12.5 MHz.
2.
No wait : Wait bit = “1”.
Wait 1 : The external memory area is accessed with wait bit = “0” and wait selection bit = “1”.
Wait 0 : The external memory area is accessed with wait bit = “0” and wait selection bit = “0”.
