8.5.7
The ERASEP command erases the specified number of
rows of code memory from the specified base address.
The specified base address must be a multiple of 0x40.
Once the erase is performed, all targeted words of
code memory contain 0xFFFFFF.
Expected Response (2 words):
0x1900
0x0002

ERASEP COMMAND
The ERASEP command cannot be used to
erase the Configuration registers or
device
code-protect Configuration registers can
only be erased with ERASEB, while the
device ID is read-only.

8.5.8
The QBLANK command queries the programming
executive to determine whether the contents of code
memory is 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 0x0 and
advances toward larger addresses for the specified
number of instruction words.
The QBLANK command 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):
0x1AF0
0x0002
Expected Response (2 words for non-blank device):
0x1A0F
0x0002

QBLANK COMMAND
The QBLANK command does not check
the system Configuration registers. The
READD command must be used to
determine the state of the Configuration
registers.
