NVM Address Register
As with Flash program memory, the NVM Address
Registers, NVMADRU and NVMADR, form the 24-bit
Effective Address (EA) of the selected row or word for
data EEPROM operations. The NVMADRU register is
used to hold the upper 8 bits of the EA, while the
NVMADR register is used to hold the lower 16 bits of
the EA. These registers are not mapped into the
Special Function Register (SFR) space; instead, they
directly capture the EA<23:0> of the last table write
instruction that has been executed and selects the data
EEPROM row to erase. Figure 6-1 depicts the program
memory EA that is formed for programming and erase
operations.

Data EEPROM Operations
The EEPROM block is accessed using table read and
write operations similar to those used for program
memory. The TBLWTH and TBLRDH instructions are not
required for data EEPROM operations since the
memory is only 16 bits wide (data on the lower address
is valid only). The following programming operations
can be performed on the data EEPROM:
• Erase one, four or eight words
• Bulk erase the entire data EEPROM
• Write one word
• Read one word

Like program memory operations, the Least Significant
bit (LSb) of NVMADR is restricted to even addresses.
This is because any given address in the data
EEPROM space consists of only the lower word of the
program memory width; the upper word, including the
uppermost “phantom byte”, are unavailable. This
means that the LSb of a data EEPROM address will
always be ‘0’.
Similarly, the Most Significant bit (MSb) of NVMADRU
is always ‘0’, since all addresses lie in the user program
space.

Note 1: Unexpected results will be obtained
should the user attempt to read the
EEPROM while a programming or erase
operation is underway.
2: The C30 C compiler includes library
procedures to automatically perform the
table read and table write operations,
manage the Table Pointer and write
buffers, and unlock and initiate memory
write sequences. This eliminates the
need to create assembler macros or time
critical routines in C for each application.
The library procedures are used in the code examples
detailed in the following sections. General descriptions
of each process are provided for users who are not
using the C30 compiler libraries.
