70H
IRQ level
R/W
Read/write value indicating a selected interrupt level.
Bits[3:0] select which ISA interrupt level is used. A value of 1
selects IRQ1, 15 selects IRQ15, etc. IRQ0 is not a valid
interrupt selection
71H
IRQ type
bits[7:0]
R
Read/write value indicating which type of interrupt is used
for the IRQ selected above.
Bit[1] - Level, 1 = high, 0 = low
Bit[0] - Type, 1= level, 0 = edge
For DM9008, this register is read only, with a value of 02H
