BIT 0 nDRIVE SELECT 2
Active low status of the DS2 disk interface output.
BIT 1 nDRIVE SELECT 3
Active low status of the DS3 disk interface output.
BIT 2 WRITE GATE
Active high status of the latched WGATE output signal.
This bit is latched by the active going edge of WGATE
and is cleared by the read of the DIR register.
