SC65D02P40

The reset vector value and the interrupt vector value in test mode are useful in production test, and the

customer should set FFF0H with 00H, FFF1H with 60H, FFF2H with 04H, FFF3H with 60H to make sure the

program down load is correct, for example, the customer should add the following code in proper position:

ORG

FFF0H

DW

6000H

DW

6004H

The default value of OTP protect byte is FFH, now the content of OTP memory can be read by OTP

programmer or emulator provided by Silan. If you set OTP cipher byte as 00H, then you cannot read this OTP

memory in any method, which can protect the customer’s software copyright.

3.6 Code transmitting module

[Description]

This module is used to generate the high and low level sequence for Infrared diode control. It is comprised of

carrier generating circuit and 32-byte code transmitting buffer which will realize the exact code transmitting.
