depends on the type of command and which drive is selected. Only the drive
selected executes the command and activates the data bus in response to host I/O
reads; the drive not selected remains inactive.
A master/slave relationship exists between the two drives: device 0 is the master and
device 1 the slave. When the Master is closed (factory default, figure 2-1), the drive
assumes the role of master; when open, the drive acts as a slave. In single drive
configurations, the Master jumper must be closed.
Cable Select Option
CSEL (cable select) is an optional feature per ANSI ATA specification. Drives
configured in a multiple drive system are identified by CSEL’s value:
– If CSEL is grounded, then the drive address is 0.
– If CSEL is open, then the drive address is 1.
