The
QBLANK
command queries the programming exec-
utive to determine if the contents of code memory are
blank (contains all 鈥?鈥檚). The size of code memory to
check must be specified in the command.
The Blank Check for code memory begins at 0x0 and
advances toward larger addresses for the specified
number of instruction words.
QBLANK returns a QE_Code of 0xF0 if the specified
code memory and code-protect bits are blank;
otherwise, QBLANK returns a QE_Code of 0x0F.
Expected Response (2 words for blank device):
0x1AF0
0x0002
Expected Response (2 words for non-blank device):
0x1A0F
0x0002
Note:
The
QBLANK
command does not check
the system operation Configuration bits
since these bits are not set to 鈥?鈥?when a
Chip Erase is performed.
The
PROGW
command instructs the programming exec-
utive to program one word of code memory (3 bytes) to
the specified memory address.
After the word has been programmed to code memory,
the programming executive verifies the programmed
data against the data in the command.
Expected Response (2 words):
0x1600
0x0002
