From now on, it will be assumed that AD2 to AD6 will
contain the intended EEPROM page address after page
setup.

EAD BYTE
Since ADDR auto-increments after a read cycle regardless
of the page boundary, successive bytes can efficiently be
read by repeating the last instruction.

latches, the corresponding bytes in the page should
previously have been erased.
The EEPROM latches are preset as described in
Section 7.5.1. The actual transfer to the EEPROM is then
performed as shown in Table 20.
The last instruction also starts Timer 2. The data in the
EEPROM latches are ORed with that in the corresponding
page bytes within 5 ms. A single-byte write is simply a
special case of ‘write page’.
ADDR auto-increments after the write cycle. If AD0 and
AD1 addressed EEPROM Latch 3 prior to the write cycle,
ADDR will point to the next EEPROM page (by bits AD2
to AD6) and to EEPROM Latch 0 (by bits AD0 and AD1).
This allows efficient coding of multi-page write operations.

WRITE PAGE
The EEPROM latches are preset as described in
Section 7.5.1. The page byte corresponding to the
asserted flags (among F0 to F3) are erased and re-written
with the contents of the respective EEPROM latches.
The last instruction also starts Timer 2. Erasure takes
5 ms upon which Timer Register T2 reloads for another
5 ms cycle for writing. The top cycles together take 10 ms.
A single-byte erase/write is simply a special event of
‘erase/write page’.
ADDR auto-increments after the write cycle. If AD0 and
AD1 addressed EEPROM Latch 3 prior to the write cycle,
ADDR will point to the next EEPROM page (by AD2 to
AD6) and to EEPROM Latch 0 (by AD0 and AD1).
This allows efficient coding of multi-page erase/write
operations.
