Functional Description
TABLE 5-12. BCSR2 Description
Board Revision Number (0:3). This field represents the revision code,
hard-assigned to the ADS. See
on page 61
, for revisions' encoding.
Software Option 2. This is the LSB of the field. Shows the state of a
dedicated dip-switch providing an option to manually change a program
flow. For the setting of dip-switch see.
Flash Presence Detect(7:5). These lines are connected to the Flash SIMM
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
