Note: t
fcyc
indicates the period of one cycle of the FLCTL clock.
t
wfcyc
indicates the period of one cycle of the FLCTL clock when the value of the NANDWF bit
is 0. On the other hand, t
wfcyc
indicates the period of two cycles of the FLCTL clock when the
value of the NANDWF bit is 1.
t
pcyc
indicates the period of one cycle of the peripheral clock (P
).
