FUNCTION
Head select. This open drain output determines which disk drive
head is active.
Logic 1 = side 0
Logic 0 = side 1
Diskette change. This signal is active low at power on and
whenever the diskette is removed. This input pin is pulled up
internally by a 1 K
resistor. The resistor can be disabled by bit 7
of L0-CRF0 (FIPURDWN).
