code word do not have a binary pattern of 01010, the message
sequence control processor will immediately halt the BC's oper-
ation. In addition, if enabled, a BC TRAP OP CODE interrupt will
be issued. Also, if enabled, a parity error will result in an OP
CODE PARITY ERROR interrupt. TABLE 37 describes the
Condition Codes.

Generate an interrupt if the condition flag tests TRUE, otherwise
continue execution at the next OpCode in the instruction list.
The passed parameter (Interrupt Bit Pattern) specifies which of
the ENHANCED BC IRQ bit(s) (bits 5-2) will be set in Interrupt
Status Register #2. Only the four LSBs of the passed parameter
are used. A parameter where the four LSBs are logic "0" will
not generate an interrupt.
Executes the message at the specified Message Control/Status
Block Address if the condition flag tests TRUE, otherwise con-
tinue execution at the next OpCode in the instruction list.

Compare Time Value to Frame Time Counter. The LT/GP0 and
EQ/GP1 flag bits are set or cleared based on the results of the
compare. If the value of the CFT's parameter is less than the
value of the frame time counter, then the LT/GP0 and NE/GP1
flags will be set, while the GT-EQ/GP0 and EQ/GP1 flags will
be cleared. If the value of the CFT's parameter is equal to the
value of the frame time counter, then the GT-EQ/GP0 and
EQ/GP1 flags will be set, while the LT/GP0 and NE/GP1 flags
will be cleared. If the value of the CFT's parameter is greater
than the current value of the frame time counter, then the GT-
EQ/GP0 and NE/GP1 flags will be set, while the LT/GP0 and
EQ/GP1 flags will be cleared.
Stop execution of the Message Sequence Control Program until
a new BC Start is issued by the host if the condition flag tests
TRUE, otherwise continue execution at the next OpCode in the
instruction list.
Jump to the OpCode specified in the Instruction List if the con-
dition flag tests TRUE, otherwise continue execution at the next
OpCode in the instruction list.

Compare Time Value to Message Time Counter. The LT/GP0 and

compare. If the value of the CMT's parameter is less than the value
of the message time counter, then the LT/GP0 and NE/GP1 flags
will be set, while the GT-EQ/GP0 and EQ/GP1 flags will be cleared.
If the value of the CMT's parameter is equal to the value of the mes-
sage time counter, then the GT-EQ/GP0 and EQ/GP1 flags will be
set, while the LT/GP0 and NE/GP1 flags will be cleared. If the value
of the CMT's parameter is greater than the current value of the
message time counter, then the GT-EQ/GP0 and NE/GP1 flags will
be set, while the LT/GP0 and EQ/GP1 flags will be cleared.
Delay the time specified by the Time parameter before execut-
ing the next OpCode if the condition flag tests TRUE, otherwise
continue execution at the next OpCode without delay. The delay
generated will use the Time to Next Message Timer.
Jump to the OpCode specified by the Instruction List Address
and push the Address of the Next OpCode on the Call Stack if
the condition flag tests TRUE, otherwise continue execution at
the next OpCode in the instruction list. Note that the maximum
depth of the subroutine call stack is four.
