Control Registers
The control registers are the 24-bit program counter (PC), 8-bit extended control register (EXR),
8-bit condition-code register (CCR), and 64-bit multiply-accumulate register (MAC: H8S/2600
CPU only).
(1) Program Counter (PC)
This 24-bit counter indicates the address of the next instruction the CPU will execute. The length
of all CPU instructions is 16 bits (one word) or a multiple of 16 bits, so the least significant PC bit
is ignored. When an instruction is fetched, the least significant PC bit is regarded as 0.
(2) Extended Control Register (EXR)
This 8-bit register contains the trace bit (T) and three interrupt mask bits (I2 to I0).
Bit 7—Trace Bit (T): Selects trace mode. When this bit is cleared to 0, instructions are executed
in sequence. When this bit is set to 1, a trace exception is generated each time an instruction is
executed.
Bits 6 to 3—Reserved: These bits are reserved, always read as 1.
Bits 2 to 0—Interrupt Mask Bits (I2 to I0): These bits designate the interrupt mask level (0 to
7). For details refer to the relevant microcontroller hardware manual.
