February 21, This is true for all the versions I have used so datashest. February 17, Problem vanished in version 5. Fortunately all seems OK. May 15, Actually they are bits 0 to 2, I had also made the same mistake. So Bit 0 not 1 is to disable movc. But how can one set it if movc is used in the lpf936 The software will not work. May 06, Security bit 1 stops movc from the sector in which it is set, bit 2 stops erase and program, bit 3 makes device useless for ISP. 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.
There is no read option, except the way given in the post do not know if it is trueso there is no read protection bit. This means that anyone can read the code.
And there is no way to stop this. April 25, I am setting bit1’s for all sectors, cannot use bit 0.
All sectors have code except the 7th with boot code, so no one can program any one sector without full sector erase to use MOVC. And that takes of a part of useful code.
Is this logic OK? Does not look fool proof. If someone uses the last sector, I can see problems. So better to to put some program code in sector7 also?
Actually 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. I have attached the image, it is in options on main form. April 22, As per data sheet there are 8 nos 2K sectors. Each sector has 3 security bits assigned to it. As per Flashmagic there are 32 Blocks.
Each Block has 3 security bits assigned to it. Sorry if I have missed in the datasheet or User Manual. April 14, If not, please do.

April 11, Sometimes you may need more than 1 attempt. Works at bps too. March 24, I have been using RD2 for years now. This is the only way to verify that serial number is set. This is how I found out that it is not working with FM 5.
So if I had to do it twice, it was normal. Normally it gets into programming mode in one go.

But not always, even in new device. From where can one download older versions of Flashmagic? Datashwet is the debug file. I could not see any readable character in notepad. So it is obviously not text. I had to power up twice to read device ID. March 23, Nothing happens when I run. The bits do not get set and the micro resets. 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.
Boot loader version is 7. Why IAP does not work to program these bits?
