2.2.2
Figure 2.3 shows the relationship between the processing modes and general registers. This LSI
has twenty-four 32-bit general registers (R0_BANK0 to R7_BANK0, R0_BANK1 to
R7_BANK1, and R8 to R15). However, only 16 of these can be accessed as general registers R0
to R15 in one processing mode. This LSI has two processing modes, user mode and privileged
mode.
• R0_BANK0 to R7_BANK0
• R0_BANK1 to R7_BANK1
Allocated to R0 to R7 in user mode (SR.MD = 0)
Allocated to R0 to R7 when SR.RB = 0 in privileged mode (SR.MD = 1).
Cannot be accessed in user mode.
Allocated to R0 to R7 when SR.RB = 1 in privileged mode.
