Interrupt Request A:
Bits <3:0> = ISA Bus Interrupt Level
0000 = no IRQ
1000 = not valid
0001 = not valid
1001 = not valid
0010 = not valid
1010 = 10
0011 = 3
1011 = 11
0100 = 4
1100 = 12
0101 = 5
1101 = not valid
0110 = not valid
1110 = not valid
0111 = 7
1111 = 15
Bits <5:4> = ISA Bus Interrupt Output Type
00 = low, edge
10 = high, edge
01 = low, level
11 = high, level
(Note: Interrupt output type will be a function of input type and bit <6> value. Bit 4 does
not perform any internal function but should be programmed to correspond to the type
of input supplied, edge or level.)
Bit <6>: Input Polarity
0 = input is active HIGH 1 = input is active LOW
