The contents of the ACC and the data memory location addressed by R6 to
R0 are shifted left one bit, but bit 3 is shifted into CF, and bit 0 (LSB) is
replaced with "0." The same contents are loaded into the ACC.

If bit 0 of R is equal to 1, the program counter is incremented by 2 and a
skip is produced. If bit 0 of R is not equal to 1, the program counter (PC) is
incremented.
