4.5
A data EEPROM address may be read via a sequence
of core instructions (4-bit command, ‘0000’) and then
output on PGD via the 4-bit command, ‘0010’ (Shift Out
Data Holding register). The result may then be immedi-
ately compared to the appropriate data in the program-
mer’s memory for verification. Refer to Section 4.4 for
implementation details of reading data EEPROM.
4.6
The term “Blank Check” means to verify that the device
has no programmed memory cells. All memories must
be verified: code memory, data EEPROM, ID locations,
and configuration bits. The Device ID registers
(3FFFFEh:3FFFFFh) should be ignored.
A “blank” or “erased” memory cell will read as a ‘1’. So,
“Blank Checking” a device merely means to verify that
all bytes read as FFh except the configuration bits.
Unused (reserved) configuration bits will read ‘0’ (pro-
grammed). Refer to Table 5-2 for blank configuration
expect data for the various PIC18F6X2X/8X2X
devices.
Given that “Blank Checking” is merely code and data
EEPROM verification with FFh expect data, refer to
Section 4.4 and Section 4.2 for implementation details.
