PIC18F87K90 FAMILY
28.6.2
The entire data EEPROM is protected from external
reads and writes by two bits: CPD and WRTD. CPD
inhibits external reads and writes of data EEPROM.
WRTD inhibits internal and external writes to data
EEPROM. The CPU can always read data EEPROM
under normal operation, regardless of the protection bit
settings.
28.6.3
The Configuration registers can be write-protected.
The WRTC bit controls protection of the Configuration
registers. In Normal Execution mode, the WRTC bit is
readable only. WRTC can only be written via ICSP or
an external programmer.
28.7
Eight memory locations (200000h-200007h) are
designated as ID locations, where the user can store
checksum or other code identification numbers. These
locations are both readable and writable, during Nor-
mal Execution mode through the TBLRD and TBLWT
instructions, or during program/verify. The ID locations
can be read when the device is code-protected.
28.8
The PIC18F87K90 family of devices can be serially
programmed while in the end application circuit. This is
simply done with two lines for clock and data, and three
other lines for power, ground and the programming
voltage. This allows customers to manufacture boards
with unprogrammed devices and then program the
microcontroller just before shipping the product. This
also allows the most recent firmware or a custom
firmware to be programmed. For the various
programming modes, please refer to the device
programming specification.
