Function
Error Occurred Flag.
This bit indicates a message error was encountered. This bit is set when
one or more of the following conditions are true (logical-OR):
Three exceptions where register bit 0 or 1 is set without affecting bit 12
state:
Bit 1 RT-RT Command Word 2 Errors that do not assert bit 12
Bit 0 Command Word Content Error that does not assert bit 12
RT-to-RT Transfer
When logic 1, bit 11 indicates an RT-to-RT message, beginning with two
contiguous Command Words.
Illegal Gap Error
When logic 1, bit 10 indicates an illegal gap occurred on the bus, other
than Response Timeout. The IRIG-106 Standard refers to this bit as
Format Error, having the same definition.
Response Timeout.
When logic 1, bit 9 indicates a response timeout occurred. This bit is
set if an RT Status Word associated with this message failed to arrive
within the response time interval specified by bits 15-14 in the MT
Configuration Register 0x0029.
For IRIG-106 compatibility, bits 15-14 in register 0x0029 should be
initialized to 00, corresponding to a 14µs response time, as defined by
MIL-STD-1553B (12µs bus dead time).
