6.0
The data EEPROM memory is readable and writable
during normal operation over the entire V
data EEPROM memory is directly mapped in the
program memory address space.
The four SFRs used to read and write the program
Flash memory are used to access data EEPROM
memory, as well. As described in
Registers”, these registers are:
• NVMCON
• NVMADR
• NVMADRU
• NVMKEY
The EEPROM data memory allows read and write of
single words and 16-word blocks. When interfacing to
data memory, NVMADR, in conjunction with the
NVMADRU register, are used to address the
EEPROM location being accessed. TBLRDL and
TBLWTL instructions are used to read and write data
EEPROM. The dsPIC30F devices have up to 8 Kbytes
(4K words) of data EEPROM with an address range
from 0x7FF000 to 0x7FFFFE.
A word write operation should be preceded by an erase
of the corresponding memory location(s). The write
typically requires 2 ms to complete, but the write time
varies with voltage and temperature.

DATA EEPROM MEMORY
This data sheet summarizes features of
this group of dsPIC30F devices and is not
intended to be a complete reference
source. For more information on the CPU,
peripherals, register descriptions and
general device functionality, refer to the
“dsPIC30F Family Reference Manual”
(DS70046). For more information on the
device instruction set and programming,
refer to the “16-bit MCU and DSC
Programmer’s
(DS70157).

Section 5.5 “Control

DD
range. The
Manual”
A program or erase operation on the data EEPROM
does not stop the instruction flow. The user is
responsible for waiting for the appropriate duration of
time before initiating another data EEPROM write/
erase operation. Attempting to read the data EEPROM
while a programming or erase operation is in progress
results in unspecified data.
Control bit WR initiates write operations similar to
program Flash writes. This bit cannot be cleared, only
set, in software. They are cleared in hardware at the
completion of the write operation. The inability to clear
the WR bit in software prevents the accidental or
premature termination of a write operation.
The WREN bit, when set, allows a write operation. On
power-up, the WREN bit is clear. The WRERR bit is set
when a write operation is interrupted by a MCLR Reset
or a WDT Time-out Reset during normal operation. In
these situations, following Reset, the user can check
the WRERR bit and rewrite the location. The address
register NVMADR remains unchanged.
6.1
A TBLRD instruction reads a word at the current
program word address. This example uses W0 as a
pointer to data EEPROM. The result is placed in
register W4 as shown in
EXAMPLE 6-1:
MOV
MOV
MOV
TBLRDL [ W0 ], W4
Note:

#HIGH_ADDR_WORD,W1
W1
Interrupt flag bit NVMIF in the IFS0
register is set when write is complete. It
must be cleared in software.
