The drive address is 0 (Master or Single) if CSEL is low, or 1 (Slave) if CSEL is high. NOTE The WD Portfolio drive autodetects whether it is a master or slave when CSEL is driven low. Drive Active/Slave Present -------------------------- Pin 23 This open collector output is a time-multiplexed signal indicating drive active or slave present. At reset, this signal is an output from the slave drive and an input to the master drive, showing that a slave drive is present. For all times other than reset, DASP- is asserted by the master and slave drives during command execution.
