Note 1: 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>.
2: PSVPAG can have only two values (‘00’ to access program memory and FF to access data EEPROM) on
PIC24F16KL402 family devices.

Note 1: 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.
2: Table operations are not required to be word-aligned. Table read operations are permitted in the configuration
memory space.
