Note 1:
2:
Data EA<15> is always ‘1’ in this case, but is not used in calculating the program space address. Bit 15 of
the address is PSVPAG<0>.
PSVPAG can have only two values (‘00’ to access program memory and FF to access data EEPROM) on
the PIC24F16KM family.

Note 1:
2:
The LSb of program space addresses is always fixed as ‘0’ in order to maintain word alignment of data in the
program and data spaces.
Table operations are not required to be word-aligned. Table Read operations are permitted in the configuration
memory space.
