6.2.4.9
The QBLANK command queries the programming
executive to determine if the contents of code memory
are blank (contains all ‘1’s). The size of code memory
to check must be specified in the command.
The Blank Check for code memory begins at [Addr] and
advances toward larger addresses for the specified
number of instruction words.
QBLANK returns a QE_Code of 0xF0 if the specified
code memory is blank; otherwise, QBLANK returns a
QE_Code of 0x0F.
Expected Response (2 words for blank device):
0x1EF0
0x0002
Expected Response (2 words for non-blank device):
0x1E0F
0x0002

Ensure that the address range selected
excludes the configuration bytes at the top
of memory when using the QBLANK com-
mand; otherwise, a non-blank response
will be generated.
