TABLE 35. 1553B STATUS WORD
NON-TEST REGISTER FUNCTION SUMMARY
A summary of the Enhanced Mini-ACE/-ACE's 24 non-test reg-
isters follows.
Interrupt Mask Registers #1 and #2: Used to enable and dis-
able interrupt requests for various events and conditions.
Configuration Registers #1 and #2: Used to select the
Enhanced Mini-ACE's/-ACE’s mode of operation, and for soft-
ware control of RT Status Word bits, Active Memory Area, BC
Stop-On-Error, RT Memory Management mode selection, and
control of the Time Tag operation.
Start/Reset Register: Used for "command" type functions such
as software reset, BC/MT Start, Interrupt reset, Time Tag Reset,
Time Tag Register Test, Initiate protocol self-test, Initiate RAM
self-test, Clear self-test register, and Clear RT Halt. The
Start/Reset Register also includes provisions for stopping the BC
in its auto-repeat mode, either at the end of the current message
or at the end of the current BC frame.
BC/RT Command Stack Register: Allows the host CPU to
determine the pointer location for the current or most recent
message.
BC Instruction List Pointer Register: May be read to deter-
mine the current location of the Instruction List Pointer for the
Enhanced BC mode.
BC Control Word/RT Subaddress Control Word Register: In
BC mode, allows host access to the current word or most recent
