7.3 Shift instruction 7.3.1 SFR, SFRP, SFL, SFLP
7.3 Shift instruction
: Head number of the devices where shift data is stored (BIN 16 bits)
n : Number of shifts (0 to 15) (BIN 16 bits)
Function
SFR
(1) Causes a shift to the right by n bits of the 16-bit data from the device designated at .
The n bits from the upper bit are filled with 0s.
(2) When a bit device is designated for , a right shift is executed within the device range specified by digit specification.
The number of bits by which a shift is executed is the remainder of n/(specified number of bits).
For example, when n 15 and (specified number of bits) 8 bits, the remainder of 15/8 1 is "7", and the data is
shifted 7 bits.
(3) Specify any of 0 to 15 as n. If the value specified as n is 16 or greater, the remainder of n/16 is used for a shift to the
right.
For example, when n 18, the data is shifted 2 bits to the right since the remainder of 18/16 1 is 2.
