SYNTAX      [<LABEL>] SFL

OPERANDS    None

EXECUTION   TMS32020
                  (PC) + 1 . PC
                  (ACC(30-0)) . ACC(31-1)
                  0 . ACC(0)
                  Not affected by SXM bit.

            TMS320C25
                  (PC) + 1 . PC
                  (ACC(31)) . C
                  (ACC(30-0)) . ACC(31-1)
                  0 . ACC(0)
                  Affects C; not affected by SXM bit.

DESCRIPTION The SFL instruction shifts the entire accumulator left one
            bit. The least significant bit is filled with a zero. On the
            TMS32020, the most significant bit is lost. On the TMS320C25,
            the most significant bit is shifted into the carry bit (C).
            Note that SFL, unlike SFR, is unaffected by SXM.
