R.0
The contents of the ACC and the data memory location addressed by R6 to
R0 are shifted right one bit, but bit 0 is shifted into CF, and bit 3 (MSB) is
replaced with "0." The same contents are loaded into the ACC.
CF & ZF
If bit 0 of R is equal to 1 then skip

(PC) + 2; if R.0 = 1“1”
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.
If bit 1 of R is equal to 1 then skip
