ERASEP COMMAND
The ERASEP command instructs the programming
executive to page erase [NUM_PAGES] of code mem-
ory. The code memory must be erased at an “even” 512
instruction word address boundary
Expected Response (2 words):
0x1900
0x0002
4.2.11
CRCP COMMAND
The CRCP command performs a CRC-16 on the range
of memory specified. This command can substitute for
a full chip verify. Data is shifted in a packed method as
demonstrated
in
byte-wise
Least
Significant Byte first.
Example:
CRC-CITT-16 with test data of “123456789” becomes
0x29B1
Expected Response (3 words):
QE_Code: 0x1C00
Length: 0x0003
CRC Value: 0xXXXX
