Figure 2.3 General Registers
Programming Note: As the user’s R0–R7 are assigned to R0_BANK0–R7_BANK0, and after an
exception or interrupt R0–R7 are assigned to R0_BANK1–R7_BANK1, it is not necessary for the
interrupt handler to save and restore the user’s R0–R7 (R0_BANK0–R7_BANK0).
After a reset, the values of R0_BANK0–R7_BANK0, R0_BANK1–R7_BANK1, and R8–R15 are
undefined.
