Basic Function Instruction
FUN 6 D P
BSHF
(Shifts the data of the 16-bit or 32-bit register to left or to right by one bit)
Symbol
Description
When the status of clear control "CLR" is at 1, then the data of register D and FO0 will all be cleared to 0.
●
Other input signals are all in effect.
When the status of clear control is "CLR" at 0, then the shift operation is permissible. When the shift control

"EN" = 1 or "EN↑" (
left (L/R=1) by one bit. The shifted-out bit (MSB when shift to left and LSB when shift to right) for both
cases will be sent to FO0. The vacated bit space (LSB when shift to left and MSB when shift to right) due to
shift operation will be filled in by the input status of fill-in bit "INB".
