PIC18F8722 FAMILY
7.5.2
Figure 7-2 shows an example of 16-bit Word Write
mode for PIC18F8527/8622/8627/8722 devices. This
mode is used for word-wide memories which includes
some of the EPROM and Flash-type memories. This
mode allows opcode fetches and table reads from all
forms of 16-bit memory and table writes to any type of
word-wide external memories. This method makes a
distinction between TBLWT cycles to even or odd
addresses.
During
(TBLPTR<0> = 0), the TABLAT data is transferred to a
holding latch and the external address data bus is
tri-stated for the data portion of the bus cycle. No write
signals are activated.

During
(TBLPTR<0> = 1), the TABLAT data is presented on
the upper byte of the AD15:AD0 bus. The contents of
the holding latch are presented on the lower byte of the
AD<15:0> bus.
The WRH signal is strobed for each write cycle; the
WRL pin is unused. The signal on the BA0 pin indicates
the Least Significant bit of TBLPTR but it is left
unconnected. Instead, the UB and LB signals are
active to select both bytes. The obvious limitation to
this method is that the table write must be done in pairs
on a specific word boundary to correctly write a word
location.
