	20 - 23	BREVN(0:3)	Board Revision Number (0:3). This field represents the revision code,	0	R
			hard-assigned to the ADS. See TABLE 5-18. "ADS Revision Encoding"
			on page 61, for revisions’ encoding.

	24	SWOPT2	Software Option 2. This is the LSB of the field. Shows the state of a	0	R
			dedicated dip-switch providing an option to manually change a program
			flow. For the setting of dip-switch see.

	25 - 27	FLASH_PD(7:5)	Flash Presence Detect(7:5). These lines are connected to the Flash SIMM	-	R
			presence detect lines, which encode the Delay of Flash SIMM mounted on
			the Flash SIMM socket. For the encoding of FLASH_PD(4:1) see TABLE
			5-13. "Flash Presence Detect (7:5) Encoding" on page 59.

	28 - 31	FLASH_PD(4:1)	Flash Presence Detect(4:1). These lines are connected to the Flash SIMM	-	R
			presence detect lines which encode the type of Flash SIMM mounted on the
			Flash SIMM socket. For the encoding of FLASH_PD(4:1) see TABLE 5-
			14. "Flash Presence Detect (4:1) Encoding" on page 59.
