SBBB

√

Subtract ACCB From Accumulator With Borrow

Subtract the contents of the ACCB and the logical

inversion 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

subtracting. During shifting, low-order bits are zero

filled, and high-order bits are sign extended if SXM =

SBRK #

√

Subtract From Auxiliary Register Short

Immediate

Subtract

the

8-bit

immediate

value

from

the

designated auxiliary register.

√

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.
