CARD VCC AND CARD CLOCK PROGRAMMING
The CRDVCC
and ASYCLK programming options allow the system clock frequency to be matched to the card clock
frequency and to select 3V or 5V CRDVCC
supply. Table 3 shows the values of
PWRON
,
RESET
and
IO
for the possible
options. The default power reset condition is state 4 (synchronous clock and CRDVCC
=5V). All states are latched for each
output variable in programming mode at the positive transition of
CS
(see figure 20).

Note : Card clock integrity is maintained during all frequency commutations (no spikes).
State 4 is the default state at power on.
DC/DC CONVERTER AND CARD DETECTOR STATUS
The MC33560 status can be polled when
CS=
L
. Please consult table 2 for a description of input and output signals.The
significance of the status message is described in table 4.
