Notes
With the exception of LDC Rm,GBR and LDC.L @Rm+,GBR, the LDC/LDC.L instructions are
privileged instructions and can only be used in privileged mode. Use in user mode will cause an
illegal instruction exception. However, LDC Rm,GBR and LDC.L @Rm+,GBR can also be used
in user mode.
With the LDC Rm, Rn_BANK and LDC.L @Rm, Rn_BANK instructions, Rn_BANK0 is
accessed when the RB bit in the SR register is 1, and Rn_BANK1 is accessed when this bit is 0.
