10 / 110 page  9 MITSUBISHI MICROCOMPUTERS M37753M8C-XXXFP, M37753M8C-XXXHP M37753S4CFP, M37753S4CHP PRELIMINAR Y Notice: This is not a final specification. Some parametric limits are subject to change. SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER STACK POINTER (S) Stack pointer (S) is a 16-bit register. It is used during a subroutine call or interrupts. It is also used during stack, stack pointer relative, or stack pointer relative indirect indexed Y addressing mode. PROGRAM COUNTER (PC) Program counter (PC) is a 16-bit counter that indicates the low-order 16 bits of the next program memory address to be executed. There is a bus interface unit between the program memory and the CPU, so that the program memory is accessed through bus interface unit. This is described later. PROGRAM BANK REGISTER (PG) Program bank register is an 8-bit register that indicates the high-or- der 8 bits of the next program memory address to be executed. When a carry occurs by incrementing the contents of the program counter, the contents of the program bank register (PG) is increased by 1. Also, when a carry or borrow occurs after adding or subtracting the offset value to or from the contents of the program counter (PC) us- ing the branch instruction, the contents of the program bank register (PG) is increased or decreased by 1, so that programs can be writ- ten without worrying about bank boundaries. DATA BANK REGISTER (DT) Data bank register (DT) is an 8-bit register. With some addressing modes, the data bank register (DT) is used to specify a part of the memory address. The contents of data bank register (DT) is used as the high-order 8 bits of a 24-bit address. Addressing modes that use the data bank register (DT) are direct indirect, direct indexed X indi- rect, direct indirect indexed Y, absolute, absolute bit, absolute in- dexed X, absolute indexed Y, absolute bit relative, and stack pointer relative indirect indexed Y. DIRECT PAGE REGISTER (DPR) Direct page register (DPR) is a 16-bit register. Its contents is used as the base address of a 256-byte direct page area. The direct page area is allocated in bank 016, but when the contents of DPR is FF0116 or greater, the direct page area spans across bank 016 and bank 116. All direct addressing modes use the contents of the direct page register (DPR) to generate the data address. If the low-order 8 bits of the direct page register (DPR) is “0016”, the number of cycles required to generate an address is minimized. Normally the low-order 8 bits of the direct page register (DPR) is set to “0016”. PROCESSOR STATUS REGISTER (PS) Processor status register (PS) is an 11-bit register. It consists of a flag to indicate the result of operation and CPU interrupt levels. Branch operations can be performed by testing the flags C, Z, V, and N. The details of each bit of the processor status register are described below. 1. Carry flag (C) The carry flag contains the carry or borrow generated by the ALU af- ter an arithmetic operation. This flag is also affected by shift and ro- tate instructions. This flag can be set and reset directly with the SEC and CLC instructions or with the SEP and CLP instructions. 2. Zero flag (Z) The zero flag is set if the result of an arithmetic operation or data transfer is zero and reset if it is not. This flag can be set and reset directly with the SEP and CLP instructions. 3. Interrupt disable flag (I) When the interrupt disable flag is set to “1”, all interrupts except ___ watchdog timer, DBC, and software interrupt are disabled. This flag is set to “1” automatically when there is an interrupt. It can be set and reset directly with the SEI and CLI instructions or SEP and CLP in- structions. 4. Decimal mode flag (D) The decimal mode flag determines whether addition and subtraction are performed as binary or decimal. Binary arithmetic is performed when this flag is “0”. If it is “1”, decimal arithmetic is performed with each word treated as 2- or 4- digit decimal. Arithmetic operation is performed using four digits when the data length flag m is “0” and with two digits when it is “1”. Decimal adjust is automatically per- formed. (Decimal operation is possible only with the ADC and SBC instructions.) This flag can be set and reset with the SEP and CLP instructions. |
