Performs AGU-To-RegisterFile data transfer, i.e. writes data contained in the AGU accumulator the to low bank of Rd via port 4 (P4 in microcode below) according to BS (bank select). The high part of the register is set to zero if enabled by BS. The instruction is stack conditioned.

Microcode Pattern:

Takes 2 cycles to execute.
