PIC18F87K90 FAMILY
The data EEPROM, for practical purposes, can be
regarded as a peripheral device because it is
addressed and accessed through a set of control
registers.
Additional detailed information on the operation of the
Flash program memory is provided in Section 7.0
“Flash Program Memory”. The data EEPROM is
discussed separately in Section 8.0 “Data EEPROM
Memory”.
