Additional register-to-register move instructions include the TFR and
SXT.L instructions for data ALU registers (see Table 4-31 on page 4-30)
and the TFRA instruction for AGU registers (see Table 4-35 on
page 4-41).

MOVEU.W HWS,HWS
Move pointer register to data ALU register.
Zero extend the 24-bit value contained in the
RRR register.
This instruction swaps the value in the R0, R1,
N, and M01 registers with their shadow regis-
ters. It is the only instruction that accesses the
shadow registers.
