Read Enable. Active low read enable. When asserted, data is
transferred from the selected device onto the data bus. Connect to
ADDP RDB.
Write Enable. Active low write enable. When asserted, data is
transferred from the data bus into the selected device. Connect to
ADDP WRB.
ADDP Chip Select. Active low output select ADDP when asserted.
Connect to ADDP CSB.
ADDP Interrupt Request 1. Active low input asserted to request
interrupt servicing by the ADDP. Connect to ADDP IRQ1.
ADDP Interrupt Request 2. Active low input asserted to request
interrupt servicing by the ADDP. Connect to ADDP IRQ2.
