TABLE B1-2. P1 - System Expansion - Interconnect Signals

Pin No.	Signal Name	Attribute	Description


C32	N.C.	-	Not Connected


D1	GND	P	Digital Ground. Connected to main GND plane of the ADS.

D2

D3

D4	EXPWE0b	O	Expansion Write Enable (0:1) (L). This are buffered GPCM Write
			Enable lines (0:1). They are meant to qualify writes to GPCM
D5	EXPWE1b
D5	EXPWE1b		controlled 8/16 data bus width memory devices. This to provide
			eased access to various communication transceivers.
			EXPWE0b controls EXPD(0:7) while EXPWE1b controls
			EXPD(8:15). These lines may also function as UPM controlled
			Byte Select Lines, which allow control over almost any type of
			memory device.

D6	GND	P	Digital Ground. Connected to main GND plane of the ADS.

D7	EXPGL0b	O	Expansion General Purpose Lines (0:5). These are buffered
			GPL(0:5)b lines which assist UPM control over memory device if
D8	EXPGL1b
D8	EXPGL1b		necessary. These are output only signals and therefore, do not
			support H/W controlled UPM waits (GPL4 as such UPWAIT).
D9	EXPGL2b		support H/W controlled UPM waits (GPL4 as such UPWAIT).
D9	EXPGL2b

D10	EXPGL3b

D11	EXPGL4b

D12	EXPGL5b

D13	GND	P	Digital Ground. Connected to main GND plane of the ADS.

D14	V3.3	P	3.3V Power Out. These lines are connected to the main 3.3V
			plane of the MSC8101ADS, this, to provide 3.3V power where
			necessary for external tool connected. The amount of current
			allowed to be drawn from this power bus is found in TABLE 7-1.
			"Off-Board Application Maximum Current Consumption" on
			page 66.

D15	EXPCTL0	O	Expansion Control Line 0. This line is a buffered version of
			MSC8101’s BCTL0 (Bus Control Line 0) which serves as R~/W,
			provided for expansion board’s use.
