Note: * Initial value is set at power-on-reset or manual-reset.
2.1.2
There are 16 general registers, designated R0 to R15. General registers R0 to R7 are banked
registers, with a different R0 to R7 register bank (R0_BANK0 to R7_BANK0 or R0_BANK1 to
R7_BANK1) being accessed according to the processor mode. For details, see figure 2.1.
The general register configuration is shown in figure 2.2.

Notes:
1.
2.
R0 functions as an index register in the indexed
register-indirect addressing mode and indexed
GBR-indirect addressing mode. In some instructions,
only R0 can be used as the source register or
destination register.
R0 to R7 are banked registers.
In privileged mode, SR.RB specifies which banked registers are
accessed as general registers (R0_BANK0 to R7_BANK0 or
R0_BANK1 to R7_BANK1).
