Preliminary
CMOS - Transmit Timing
Figure 58 is a timing diagram which shows the detailed
requirements for the CMOS output signals. The SIO0 signal
is driven once per t
CYCLE1
interval on the falling edge. The
clock-to-output window is t
Q1,MIN
/t
Q1,MAX.
The SCK and
SIO0 timing points are measured at the 50% level. The rise
and fall times of SIO0 are t
QR1
and t
QF1
, measured at the
20% and 80% levels.
