PIC24FV32KA304 FAMILY
6.4.3
To read a word from data EEPROM, the table read
instruction is used. Since the EEPROM array is only
16 bits wide, only the TBLRDL instruction is needed.
The read operation is performed by loading TBLPAG
and WREG with the address of the EEPROM location
followed by a TBLRDL instruction.
EXAMPLE 6-5:
DS39995B-page 72
int __attribute__ ((space(eedata))) eeData = 0x1234;
int data;
unsigned int offset;
// Set up a pointer to the EEPROM location to be erased
TBLPAG = __builtin_tblpage(&eeData);
offset = __builtin_tbloffset(&eeData);
data = __builtin_tblrdl(offset);
READING THE DATA EEPROM
READING THE DATA EEPROM USING THE TBLRD COMMAND
// Data read from EEPROM
A typical read sequence, using the Table Pointer
management
builtin_tbloffset)
(builtin_tblrdl) procedures from the C30
compiler library, is provided in
Program Space Visibility (PSV) can also be used to
read locations in the data EEPROM.
// Global variable located in EEPROM
// Initialize EE Data page pointer
// Initizlize lower word of address
// Write EEPROM data to write latch
