3. PROGRAM MEMORY (ROM) ……… 1002 STEPS
×
10 BITS
The program memory (ROM) is configured in 10 bits steps. It is addressed by the program counter.
Program and table data are stored in the program memory.

5 bits. The data memory stores processing data. In some cases, the
data memory is processed in 8-bit units. R

may be used as the data pointer for the ROM.
After power application, the RAM will be undefined. The RAM retains the previous data on reset.

Caution
Avoid using the RAM areas R

, and R

in a CALL routine as much as possible because these
areas are also used as stack memory areas (to prevent program hang-up in case the value of
the SP is destroyed due to some reason such as noise).
When using these RAM areas as general-purpose RAM areas, be sure to include stack pointer
checking in the main routine.
