4. ATA Drive Register Set Definition and Protocol
The CompactFlash Memory Card can be configured as a high performance I/O device through the following ways:
The communication to or from the CompactFlash Memory Card is done using the Task File registers, which provide
all the necessary registers for control and status information. The PCMCIA interface connects peripherals to the host
using four register mapping methods. Table 4-1 is a detailed description of these methods.
