6.5
The minimum programming block is 32 words or
64 bytes. Word or byte programming is not supported.
Table writes are used internally to load the holding
registers needed to program the Flash memory. There
are 64 holding registers used by the table writes for
programming.
Since the Table Latch (TABLAT) is only a single byte, the
TBLWT instruction may need to be executed 64 times for
each programming operation. All of the table write
operations will essentially be short writes because only
the holding registers are written. At the end of updating
the 64 holding registers, the EECON1 register must be
written to in order to start the programming operation
with a long write.
The long write is necessary for programming the
internal Flash. Instruction execution is halted while in a
long write cycle. The long write will be terminated by
the internal programming timer.

TBLPTR = xxxxx0
If the section of program memory to be written to
has been programmed previously, then the
memory will need to be erased before the write
occurs (see Section 6.4.1 “Flash Program
Memory Erase Sequence”).
Write the 64 bytes into the holding registers with
auto-increment.
Set the WREN bit to enable byte writes.
Disable interrupts.

The EEPROM on-chip timer controls the write time.
The write/erase voltages are generated by an on-chip
