Table 375. ISP Blank check sector command
Command I
Input Start Sector Number:
End Sector Number: Should be greater than or equal to start sector number.
Return Code CMD_SUCCESS |
SECTOR_NOT_BLANK (followed by <Offset of the first non blank word location>
<Contents of non blank word location>) |
INVALID_SECTOR |
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.
Table 376. ISP Read Part Identification command
Command J
Input None.
Return Code CMD_SUCCESS followed by part identification number in ASCII (see Table 377
“LPC11U3x/2x/1x device identification numbers”).
Description This command is used to read the part identification number.
