Notes:
1.	I/O types:
		IA, IB = Digital input; OA, OB = Digital output (see Table 3-9).
		I(DA) = Analog input; O(DD), O(DF) = Analog output (see Table 3-10).
		DI = Device interconnect.
2.	NC = No external connection allowed (may have internal connection).
3.	Interface Legend:
		MDP = Modem Data Pump
		BIF = Bus Interface Device
		ISDN = ISDN U or S/T interface device.
