So if I had to do it twice, it was normal. May 15, Products are not datashwet for use in such applications unless Integrated Silicon Solution, Inc. I am setting bit1’s for all sectors, cannot use bit 0.

Please login or register. There are 32 intensity levels with the lowest set as the power on default. February 17, Home Help Search Login Register. Since it takes 2 steps to program the security and clock bit by flashmagic security bit does not set if clock bit programed in same programed cycleI had tried this.

Do not turn on the power supply until all connections are completed. Each Block has 3 security bits assigned to it. ISSI reserves the right to make changes to this specification and its products at any time without notice. Why IAP does not work to program these bits?


The device regulates the LED load current is set using an external, low value sensing resistor. Note that you can only see posts made in areas you currently have access to. Sorry if I have missed in the datasheet or User Manual.

Problem vanished in version 5. Input operating voltage range is 2. Normally it gets into programming mode in one go. The software will not work. Each sector has 3 security bits assigned to it. Boot loader version is 7.

LPC Brownout issues

Fortunately all seems OK. This is the only way to verify that serial number is set. Sometimes you may need more than 1 attempt. Does not look fool proof. March 23, The bits do not get set and the micro resets. And there is no way to stop this.

February 21, If the current exceeds 2A, please check for circuit fault. As per data sheet there are 8 nos 2K sectors. But not always, even in new device. This is true for all the versions I have used so far. Datasueet later I realized that I can select only 8 out of 32 for LPC, perhaps the list is for upto any 64K device for future. So it is obviously not text. There is no read option, except the way given in the post do fatasheet know if it is trueso there is no read protection bit.


April 25, So better to to put some program code in sector7 also? If not, please do.

So with movc to use and ISP to be enabled, only bit 2 set in all sectors except the one with ISP, can be a bit of help. This means that anyone can read the code. Actually they are bits 0 to 2, I had also made the same mistake. So Bit 0 not 1 is to disable movc. March 24, ,
