PIC24F16KA102 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:
DS39927B-page 56
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
Preliminary
A typical read sequence, using the Table Pointer manage-
ment (builtin_tblpage and builtin_tbloffset)
and table read (builtin_tblrdl) procedures from the
C30 compiler library, is provided in Example 6-5.
Program Space Visibility (PSV) can also be used to
read locations in the data EEPROM.
// Variable located in EEPROM
// Initialize EE Data page pointer
// Initizlize lower word of address
// Write EEPROM data to write latch
