Detect revision '-' or newer by software?

Is it somehow possible to detect if a LPC4357 with rev '-' is used or a newer version?

Perhaps some register or content of a register which was not available in LPC4357 Rev '-'?

Or has someone checked e.g. to write to one register of peripheral X and read back a register of peripheral Y
to see the (hard) problem mentioned in errata? Or is it only happening seldom and cannot be used for a check?

Can it perhaps be recognized by SCB-> CPUID?

Background: I want to display a big warning if a rev '-' is used and perhaps even deny normal operation.

Hi,

You can determine by reading the bootcode version.
LPC4357 rev' '-' parts have boot code version 12.1
The boot code version number can be found using ISP or IAP calls.
