NOTE:

CLKOUT

synchronization

occurs

on

the

rising

edge

of

RESIN

.

If

RESIN

is

sampled

high

while

CLKOUT

is

high

(solid

line),

then

CLKOUT

will

remain

low

for

two

CLKIN

periods.

If

RESIN

is

sampled

high

while

CLKOUT

is

low

(dashed

line),

then

CLKOUT

will

not

be

affected.
