2.1.2
The 32-bit control registers consist of the 32-bit status register (SR), global base register (GBR),
and vector base register (VBR). The status register indicates processing states. The global base
register functions as a base address for the indirect GBR addressing mode to transfer data to the
registers of on-chip peripheral modules. The vector base register functions as the base address of
the exception processing vector area (including interrupts). Figure 2.2 shows a control register.

Reserved bits. This bit always read 0.
The write value should always be 0.
Bits I0–I3: Interrupt mask bits.

Reserved bits. 0 is read. Write only.
Global base register (GBR):
Indicates the base address of the indirect
GBR addressing mode. The indirect GBR
addressing mode is used in data transfer
for on-chip peripheral modules register
areas and in logic operations.
Vector base register (VBR):
Stores the base address of the exception
processing vector area.
BT (BT/S), BF (BF/S), SETT, and CLRT
instructions use the T bit to indicate true
(1) or false (0). The ADDV, ADDC,
SUBV, SUBC, NEGC, DIV0U, DIV0S,
DIV1, SHAR, SHAL, SHLR, SHLL,
ROTR, ROTL, ROTCR, and ROTCL
instructions also use the T bit to indicate
carry/borrow or overflow/underflow.
and DIV1 instructions.
