Reading Sector Data from CompactFlash Control
Flow Process
Sector data can be read from the CompactFlash device via
the MPU interface of the System ACE CF controller by fol-
lowing the control flow sequence shown in Figure 22. The
first step in the sequence of accessing the CompactFlash
interface is to arbitrate for a lock. The control flow process
for obtaining a CompactFlash resource lock is shown in
Figure 23, page 43. Once the MPU interface has been
granted a CompactFlash lock, the MPU interface needs to
make sure that the CompactFlash device is ready to receive
a command. The process for polling the command readi-
ness indicator is shown in Figure 24, page 44.
