TABLE 50. 1553B STATUS WORD
NON-TEST REGISTER FUNCTION SUMMARY
A summary of the PCI Mini-ACE Mark3/Micro-ACE TE’s 24 non-
test registers follows.
INTERRUPT MASK REGISTERS #1 AND #2
Interrupt Mask Registers #1 and #2 are used to enable and dis-
able interrupt requests for various events and conditions.
CONFIGURATION REGISTERS #1 AND #2
Configuration Registers #1 and #2 are used to select the PCI
Mini-ACE Mark3/Micro-ACE TE’s mode of operation, and for
software 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. Note that the LEVEL/PULSE
INTERRUPT REQUEST bit in Configuration Register #2 MUST
be set to 1 for correct PCI operation.
START/RESET REGISTER
The Start/Reset Register is used for "command" type functions
such as software reset, BC/MT Start, Interrupt reset, Time Tag
Reset, Time Tag Register 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,
NOTE: Please see Appendix “F” of the Enhanced Mini-ACE
User’s Guide for important information applicable only to RT
MODE operation, enabling of the interrupt status queue and
use of specific non-message interrupts.
