DATA EEPROM MEMORY
The EEPROM data memory is readable and writable
during normal operation (full V
DD
range). This memory
is not directly mapped in the register file space.
Instead, it is indirectly addressed through the Special
Function Registers. There are four SFRs used to read
and write this memory:
EECON1
EECON2 (not a physically implemented register)
EEDAT
EEADR
EEDAT holds the 8-bit data for read/write, and EEADR
holds the address of the EEPROM location being
accessed. The PIC16F785 has 256 bytes of data
EEPROM with an address range from 0h to FFh.
The EEPROM data memory allows byte read and write.
A byte write automatically erases the location and
writes the new data (erase before write). The EEPROM
data memory is rated for high erase/write cycles. The
write time is controlled by an on-chip timer. The write
time will vary with voltage and temperature, as well as
from chip-to-chip. Please refer to AC Specifications in
Section 18.0 “Electrical Specifications”
for exact
limits.
When the data memory is code-protected, the CPU
may continue to read and write the data EEPROM
memory. The device programmer can no longer access
the data EEPROM data and will read zeroes.
Additional information on the data EEPROM is
available in the PICmicro
Mid-Range Reference Man-
ual, (DS33023).
