*R:Read only W: One time programmable (OTP) R/W: readable and one time programmable (OTP) R/W/E: readable and rewritable if not locked. Data Flash range is programmed & verified with 32-bit precision. Any configurations listed under Device-Specific’ in the menu item Device-> Settings will be written to the DUT during ‘Program’ operation regardless of memory range selection. Special Device Considerations:
| Option | Description |
| Security Flag | Set Bit 5 to 0 will disable Erase. Set Bit 6 to 0 will disable Program. Set Bit 7 to 0 will disable Read.Bits 4 to 0 are reserved and should be set to 1s.The Security Byte cannot be erased and once bit 5 is programmed to 0the whole chip is secured and no further operations can be performed. |
| 1. | Verification for this device is performed using the internal CRC feature of the device. | |||||||||||||
| The Data Pattern CRC is compared and validated against the CRC value returned internally by the device. | ||||||||||||||
| Device specifications provide details on how this CRC is calculated. | ||||||||||||||
| 2. | Renesas Flash Programmer Image File (*.rpi) file format support added with features of ISEID code Option bytes. | |||||||||||||
| 3. | FlashOptions should be in correct-format in RPI file. | |||||||||||||
| 4. | The Security Flag and ID code can be set in the Secure command. | |||||||||||||
| 5. | Once ID code has been set under the Secure command. | |||||||||||||
| the sample will check ID Authentication during all standard operations.it cannot be reset. | ||||||||||||||
| 6. | This algorithm supports Firmware version RH850 V3 or later. | |||||||||||||
| 7. | Once Validate ICU-S is set to True(i.e enabled ICU-S/ISE under FlashOptions).Stand-alone verify and compare will not be supported in the Data Flash range. | |||||||||||||
| 8. | Serialization is not supported. | |||||||||||||
| 9. | Loading an .rpi file automatically sets configurations and security. Configuration inputs are overwritten and cannot be changed.
| |
ID Code bytes can only be programmed by loading an .rpi file with ID protection set(check RPI file thoroughly).
| 10. |
Unprogrammed parts of the Data Flash will be in the erased state and readback data is in an unkown state. |
11. |
Connect processing routines will attempt to unlock during every operation if the ID the is programmed once. |
|
And the Algo will read the deviceID/Electronic DevID as 00000000 if the ID Code Authentication Mode Get fails (i.e wrong ID Code password in RPI fileso don’t ignore the ID check). |

BPM does not sell programmable devices, nor do we program devices directly. BPM makes programmers and accessories to make programming in-house fast, easy, and profitable.
