μPD17062 2. PROGRAM MEMORY (ROM) Program memory stores the program to be executed by the CPU, as well as predetermined constant data. 2.1 CONFIGURATION OF PROGRAM MEMORY Fig. 2-1 shows the configuration of program memory. As shown in Fig. 2-1, the capacity of the program memory is 8K bytes (3968 × 16 bits). Locations in program memory are addressed in units of 16 bits. The total address range is from 0000H to 0F7FH. Memory is divided into pages. The range of page 0 is from 0000H to 07FFH,

μPD17062 2.2 FUNCTIONS OF PROGRAM MEMORY Program memory has two basic functions: (1) Program storage (2) Constant data storage A program is a set of instructions that control the CPU (Central Processing Unit: Device that actually controls the microcontroller). The CPU executes processing sequentially according to the instructions coded in the program. The CPU sequentially reads instructions from the program stored in program memory and executes processing according to each instruction. Ea

μPD17062 2.4 BRANCHING A PROGRAM A program is branched by execution of the branch instruction (BR). Fig. 2-2 illustrates the operation of the branch instruction. Branch instructions (BR) are divided into two types. Direct branch instructions (BR addr) transfer control to a program memory address (addr) directly specified in its operand. Indirect branch instructions (BR @AR) transfer control to a program memory address specified in an address register (AR), described below. See also Chapter 3
