5.14.9 BCSR8 Board Miscellaneous Register 1

On the board, the BCSR8 acts as a reserved control register. The BCSR8, which may be read or
written at any time, receives its defaults upon Power-On-Reset. The BCSR8 fields are described
below in Table 5-18.

5.14.10 BCSR9 Board Control Miscellaneous Register 2

On the board, the BCSR9 acts as a control register for FA mode. The BCSR9, which may be read
or written at any time, receives its defaults upon Power-On-Reset. The BCSR9 fields are
described below in Table 5-19.

PTMC Buffers Enable. Used to control the PTMC card buffer enable
logic in order to prevent undesired signal contention on the ADS. Low
enables buffers. High isolates PTMC card output driver from the base
board.
Configuration Lock. Allows locking of the values of control registers
until power down. The bit is activated when low. High is a default
mode when configuration bits are rewritten from the DIP-switches.

FA Mode. Two bits define different FA module operation modes. They
are affected when the FA Module is activated. Default mode - FA
module is disabled
FA_M3 Mode. Two bits define the different FA_M3 module operation
modes. They are affected when the FA_M3 Module is activated.
Default mode - FA_M3 module is disabled.
FA Module Activation. High with PORESET places FA Module in
operation mode.
FA_M3 Module Activation. High with PORESET places FA_M3
Module in operation mode.
