The data memory is the Flash data memory block,
which attaches to the user Flash program memory. It is
located at addresses 0x400-0x43F, as shown in Figure
5-1.
This Flash data memory block consists of 8 rows and
has self-write capability of up to 64 bytes. This memory
block is not directly mapped in the register 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 is
EEADR + 400h with only the lower 8 bits of each word
being readable or writable.
• EEADR = 00h, PC = 400h
• EEADR = 01h, PC = 401h
The Flash data memory allows byte read and write, and
during the operations of read and write cycles, the CPU
stalls.
The timing for all self-writes and erases is controlled by
the internal timing block of the program memory (see
Section 14.0
Table 14-11). The write/erase voltages are generated
by an on-chip charge pump rated to operate over the
voltage range of the device for byte or word operations.
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.
