Notes:
1. CD1# and CD2# are grounded internal to PC Card.
2. Shows density for which specied address bit is MSB. Higher order address bits are
no connects (i.e., 1MB A19 is MSB, A20 - A21 are NC).
3. BVD1 is an open drain output with a 10K ohm internal pull-up resistor.
4. Address bit 22 is used for the 8MB cards as well as the 6MB Cards.
