5-2. System Microprocessor

The system microprocessor QL002 employs an 8 bit micro-controller (HD64F3337YF16).

In this system microprocessor, a program area is pro- vided inside the non-volatile memory.

Using an exclusive data-writer allows easy maintenance of the system microprocessor when specification modifi- cation, bug correction, etc. will occur.

Table 5-2-1 shows the terminal functions of the system microprocessor.
