The CFC does not support the true IDE mode yet. However, memory space
is reserved for future expansion.
The CFC contains a control register to reset the CompactFlash card, a status
register, and a configuration register.
Table 50 lists the CFC controller registers. Table 51 through Table 53 describe
the register bits.
