Description
This instruction shifts the data field of the Instruction. N2HET pins can be
used for data in or data out. SHFT includes parameters to select the shift
direction (in, out, left, right), shift condition (shift on a defined clock edge on
HET[0] or shift always), register for data storage (A, B, R, S or T), and the
data pin.
