Bit field descriptions for the Protected Flash Region

gvellet — Fri, 28 Jun 2024 20:16:29 GMT

Hi,

In the LPC55S69 user manual UM11126 page 252, it is written "Note: For bit field descriptions, see the attached Protected Flash Region.xls for further details." Where can I find this excel file?

In the MCUXpresso Secure Provisioning tool, some information is given for the bitfield but it is not detailed.

For instance, in the location CMPA:SPI_FLASH_CFG, the bit field "SPI_RECOVERY_BOOT_EN" is 5-bit with no explanation. In the user manual, the same bitfield is said to have only 4-bit. Obviously the protected Flash bit fields are updated faster than the user manual.

Perhaps for designers with NXP device experience, most of these details are obvious. But for a new comer like me, I stumble a lot trying to understand this device.

Thanks

Hi Alice,

In the current UM11126 file, there is no attachment. Can you attached the xls file to this message thread?

Thanks,
