Redundant instruction
This is a redundant instruction. It is replaced by: SHR
Shifts one hexadecimal digit (4 bits) of the 16-bit area specified by d to the left (to the higher digit position) if the trigger EN is in the ON-state.
Output
16-bit area to be shifted to the left
When one hexadecimal digit (4 bits) is shifted to the left,
hexadecimal digit position 3 (bit position 12 to 15) of the data specified by d is shifted out and is transferred to sys_wDigitShiftedOut.
hexadecimal digit position 0 (bit position 0 to 3) of the 16-bit area specified by d becomes 0.
This instruction is useful when the hexadecimal or BCD data is handled.
