PARAM_ERROR

Description This command is used to blank check one or more sectors of on-chip flash memory.

Blank check on sector 0 always fails as first 64 bytes are re-mapped to flash boot block.

When CRP is enabled, the blank check command returns 0 for the offset and value of sectors which are not blank. Blank sectors are correctly reported irrespective of the CRP setting.

Example "I 2 3<CR><LF>" blank checks the flash sectors 2 and 3.
