Usage (How to Write the Program)
This chapter describes how to write programs with a PROM programmer. For the operation of the PROM programmer, refer to
the user's manual of the PROM programmer.
2.1 Programming Procedures
Follow these procedures (1) through (8) to write programs into the MCU.
(1) Read the program into the PROM programmer.
1) For M306V0EE, M306V2EE
• OSD ROM, internal ROM: offset (80000h) required
2) For M306XXEC
• Internal ROM: offset (C0000h) required
3) For other MCUs
• Internal ROM: offset (E0000h) required
↓
(2) Attach the adapter to the PROM programmer. (See Section 2.2)
↓
(3) Set the JP1 switch. (See Section 2.3)
↓
(4) Insert the MCU into the adapter. (See Section 2.4)
↓
(5) Specify the programming area of the MCU using the PROM programmer.
(See Section 2.5) *1
↓
(6) Using the PROM programmer's erase check function, check whether data can be written
into the MCU's programming area. *2
↓
(7) Write the program into the programming area of the MCU using the PROM
programmer. *2
↓
(8) Verify the programming area of the MCU using the PROM programmer to check whether
the program is written into the MCU correctly. *2
CAUTION
*1 Be sure to set the programming area. Otherwise the mode's shift to the programming mode may not be
performed successfully. The erase check function etc. may not also be performed completely.
*2 Some PROM programmers perform these steps (6) through (8) automatically.
