SBBB
√
Subtract ACCB From Accumulator With Borrow
Subtract the contents of the ACCB and the logical in-
version of the carry bit from the accumulator. The result
is stored in the accumulator; the accumulator buffer is
not affected. Clear the carry bit if the result generates
a borrow.
SBLK # lk [ , shift ]
√ √ √
Subtract From Accumulator Long Immediate
With Shift
Subtract the immediate value from the accumulator. If
a shift is specified, left shift the value before subtract-
ing. During shifting, low-order bits are zero filled, and
high-order bits are sign extended if SXM = 1.
SBRK # k
√ √ √
Subtract From Auxiliary Register Short
Immediate
Subtract the 8-bit immediate value from the
designated auxiliary register.
SC
√ √ √
Set Carry Bit
Set the C status bit to 1.
SETC control bit
√ √
Set Control Bit
Set the specified control bit to a logic 1. Maskable
interrupts are disabled immediately after the SETC
instruction executes.
SFL
√ √ √
Shift Accumulator Left
Shift the contents of the accumulator left one bit.
SFLB
√
Shift ACCB and Accumulator Left
Shift the concatenation of the accumulator and the
ACCB left one bit. The LSB of the ACCB is cleared to
0, and the MSB of the ACCB is shifted into the carry bit.
SFR
√ √ √
Shift Accumulator Right
Shift the contents of the accumulator right one bit. If
SXM = 1, SFR produces an arithmetic right shift. If
SXM = 0, SFR produces a logic right shift.
SFRB
√
Shift ACCB and Accumulator Right
Shift the concatenation of the accumulator and the
ACCB right 1 bit. The LSB of the ACCB is shifted into
the carry bit. If SXM = 1, SFRB produces an arithmetic
right shift. If SXM = 0, SFRB produces a logic right shift.
SFSM
√
Set Serial Port Frame Synchronization Mode
Set the FSM status bit to 1.
