2.2.6
For the nineteen 32-bit registers comprising general registers R0 to R14, control register GBR, and
system registers MACH, MACL, and PR, high-speed register saving and restoration can be carried
out using a register bank. Saving to the bank is performed automatically after the CPU accepts an
interrupt that uses a register bank. Restoration from the bank is executed by issuing a RESBANK
instruction in an interrupt service routine.
For details, refer to section 7, Register Banks.
