5.0
The
0x400-0x43F. It is physically attached to the Flash pro-
gram memory block. The Flash memory consists of 8
rows and has self-write capability of up to 64 bytes.
This memory block is not directly mapped in the regis-
ter file space. Instead, it is indirectly addressed through
the Special Function Registers. There are three SFRs
used to read and write this memory:
• EEDATA (Register 5-1)
• EEADR (Register 5-2)
• EECON (Register 5-3)
EEDATA holds the 8-bit data for read/write, and
EEADR holds the address of the EEDATA location
being accessed. The effective program counter
address is EEADR + 400h.
• EEADR (00h), PC (400h)
• EEADR (01h), PC (401h)

Only the lower 8 bits of each word is readable or
writable in User mode.
The Flash data memory allows byte read and write. A
byte write automatically erases the row in which the
target byte is located and writes the new data (erase
before write). During the operation of read/write, the
CPU stalls.
The write time is controlled by an on-chip timer. The
write/erase voltages are generated by an on-chip
charge pump rated to operate over the voltage range of
the device.
When the device is code-protected, the CPU may
continue to read and write the Flash data memory and
read the program memory. When code-protected, the
device programmer can no longer access data or
program memory.
