(6) Program write setting method using a general PROM programmer

PROM to be prepared should equal to TC571000D functions.

1. Set the switch (SW1) of BM11132 (hereinafter referred to as “adapter”) to the program

side (NOR) (Note 1).

2. Connect MCU to the adapter (Note 2).

3. Connect the adapter to PROM programmer (Note 2).

4. Set the PROM type of PROM programmer to TC571000D.

5.

Set the start address for writing PROM to 00000H, and the end address to 1FFFFH

(Note 3).

6. Writing to built-in one time PROM and verifying should be operated according to the

operation procedures of PROM programmer.

Note 1: If data is written to built-in one time PROM without setting the switch (SW1) to the

program side, the device would be damaged.

Note 2: Please set with the first pin of the adapter and that of PROM programmer socket

matched. If the first pin is conversely set, MCU or programmer would be damaged.

Note 3: If data “0” is written to the address which is over 1FFFFH, the contents of the original

program would be damaged because of writing “0” to the addresses 00000H to

1FFFFH.

(7) Programming flow chart

The programming mode is set by applying 12.75 V (Programming voltage) to the VPP pin

when the following pins are set as follows,

Then the data in the address is verified.

This programming procedure is repeated until correct data is read from the address. (25

times maximum)

Subsequently, all data are programmed in all addresses.

The verification for all data is done under the condition of VPP

= VCC = 5 V after all data

were written.

Figure 3.2.2 shows the programming flow chart.
