E Specifications in this manual are tentative and subject to change Mitsubishi microcomputers M30240 Group Central Processing Unit (CPU) SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER 2.0 Operation of Functional Blocks The M30240 group accommodates certain units in a single chip. These units include ROM and RAM to store instructions and data, and the central processing unit (CPU) to execute arithmetic/logic operations. Also included are peripheral units such as USB, timers, serial I/O, DMAC, CRC calculation circuit, A-D converter, and I/O ports. The following explains each unit. 2.1 Central Processing Unit (CPU) The CPU has a total of 13 registers shown in Figure 1.5. Seven of these registers (R0, R1, R2, R3, A0, A1, and FB) come in two sets; therefore, these have two register banks. b15 b8 b7 R0(Note) H b0 L b15 b8 b7 R1(Note) H b0 L b15 R2(Note) b0 Data registers b19 PC b19 INTB H b0 Program counter b0 L Interrupt table register b15 R3(Note) b0 b15 USP b0 User stack pointer b15 A0(Note) b15 A1(Note) b15 FB(Note) b0 Address b0 registers b0 Frame base registers b15 ISP b15 SB b15 FLG b0 Interrupt stack pointer b0 Static base register b0 Flag register IPL U I O B S Z D C Note: These registers consist of two register banks. Figure 1.5: Central processing unit register 2.1.1 Data registers (R0, R0H, R0L, R1, R1H, R1L, R2, and R3) Data registers (R0, R1, R2, and R3) are configured with 16 bits, and are used primarily for transfer and arithmetic/logic operations. 1-11 11 Page
