2.4 Program Memory (ROM): 1,002 Steps
× 10 Bits (
µPD67, 67A)
2,026 Steps
× 10 Bits (
µPD68, 68A)
4,074 Steps
× 10 Bits (
µPD69)
The ROM consists of 10 bits per step, and is addressed by the program counter.
The program memory stores programs and table data, etc.
The 22 steps from 7EAH to 7FFH of the
µPD67, 67A, 68, and 68A, and FEAH to FFFH of the µPD69 cannot
be used in the test program area.
Figure 2-3.

Note The unmounted area and test program area are designed so that a program or data placed in either of
them by mistake is returned to the 000H address.
