Shift/Rotate
Shifts the B register. left the indicated number of 40
bits with all vacated bit positions becoming O.
Maximum shift is 16 bits.
Test/Alter/Branch Skips to {adrs} if the B register is negative (bit 15 is
1). Setting or clearing the bit after the test can be
Test/ Alter/Branch
specified. {adrs} must be within - 32 and

31 of
the current location.
Test/Alter/Branch Skips to {adrs} if the B register is positive (bit 15 is
0). Setting or clearing the bit after the test can be

BCD Math
Shifts the B register right the indicated number of
bits with all vacated bit positions becoming O.
Maximum shift is 16 bits.
Skips to {adrs} if Decimal Carry is clear. Decimal
carry is a single bit in the processor which may
have been set by certain arithmetic operations.
{adrs} must be within - 32 and
+
31 of the cur-
rent location.
Sets DMA inwards. Reads from peripheral, writes
to memory.
Sets DMA outwards. Reads from memory, writes
to peripheral.
Skips to {adrs} if Decimal Carry is set. Decimal
carry is a single bit in the processor which may
have been set by certain arithmetic operations.
{adrs} must be with - 32 and
+
31 of the current
location.
Test/ Alter/Branch Skips to {adrs} if Extend is clear. Extend is a Single
bit in the processor which may have been set by
certain arithmetic operations. Setting or clearing
the bit after the test can be specified. {adrs} must
be within - 32 and
+
31 of the current location.
