ISP Blank check sector command
Command
I
Input
Start Sector Number:
End Sector Number:
Should be greater than or equal to start sector number.
Flash bank
: Selects flash bank if the part supports more than on bank. 0 = flash
bank A, 1 = flash bank B.
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 | INVALID_FLASH_UNIT
Description
This command is used to blank check one or more sectors of on-chip flash memory.
Example
"I 2 3 0 <CR><LF>" blank checks the flash sectors 2 and 3 in flash bank 0.
Table 45.
ISP Read Part Identification command
Command
J
Input
None.
Return Code
CMD_SUCCESS followed by part identification number in ASCII (see
“LPC43xx part identification numbers”
).
The command returns two words: word0 followed by word1. Only the 8 LSBs on
word1 contain configuration information. The top 24 MSBs should be ignored or
masked as 0s. On parts with on-chip flash, word 0 corresponds to the part id and
word1 indicates the flash configuration. On flashless parts, word0 corresponds to
the part id and word1 contains 0x0.
Description
This command is used to read the part identification number. The part identification
number maps to a feature subset within a device family. This number will not
normally change as a result of technical revisions.
