4-15 4. 3 .4 INFORMATION TRANSFER phases Note: The COMMAND, DATA, STATUS, and MESSAGE phases are all grouped together as the information transfer phases because they are a]l used to transfer data or control information via the DATA BUS The actual content of the information is beyond the scope of this section. The C/D, I/O, and MSG signals are used [...]

4-16 The INFORMATION TRANSFER phases use one or more REQ/ACK handshakes to control the information transfer Each REQ/ACK handshake allows the transfer of one byte of information. During the INFORMATION TRANSFER phases the BSY signal shall remain true and the SEL signal shall remain false. Additionally, during the INFORMATION TRANSFER phases, the ta[...]
