21 / 252 page  21 µPD17933, 17934 2.2 Program Memory Figure 2-2 shows the configuration of the program memory. As shown in this figure, the program memory consists of: µPD17933: 6144 × 16 bits (0000H-17FFH) µPD17934: 8192 × 16 bits (0000H-1FFFH) Because all “instructions” are “one-word instructions”, one instruction can be stored to one address of the program memory. As constant data, the contents of the program memory are read to the data buffer by using a table reference instruction. Figure 2-2.
