6.2
The External Memory Interface implemented in
PIC18F8X20 devices operates only in 16-bit mode.
The mode selection is not software configurable, but is
programmed via the configuration bits.
The WM<1:0> bits in the MEMCON register determine
three types of connections in 16-bit mode. They are
referred to as:
• 16-bit Byte Write
• 16-bit Word Write
• 16-bit Byte Select
These three different configurations allow the designer
maximum flexibility in using 8-bit and 16-bit memory
devices.
For all 16-bit modes, the Address Latch Enable (ALE)
pin indicates that the address bits A<15:0> are
available on the External Memory Interface bus.
Following the address latch, the Output Enable signal
(OE) will enable both bytes of program memory at once
to form a 16-bit instruction word. The Chip Enable
signal (CE) is active at any time that the microcontroller
accesses external memory, whether reading or writing;
it is inactive (asserted high) whenever the device is in
Sleep mode.

In Byte Select mode, JEDEC standard Flash memories
will require BA0 for the byte address line and one I/O
line to select between Byte and Word mode. The other
16-bit modes do not need BA0. JEDEC standard static
RAM memories will use the UB or LB signals for byte
selection.
6.2.1
Figure 6-1 shows an example of 16-bit Byte Write
mode for PIC18F8X20 devices. This mode is used for
two separate 8-bit memories connected for 16-bit oper-
ation. This generally includes basic EPROM and Flash
devices. It allows table writes to byte-wide external
memories.
During a TBLWT instruction cycle, the TABLAT data is
presented on the upper and lower bytes of the
AD15:AD0 bus. The appropriate WRH or WRL control
line is strobed on the LSb of the TBLPTR.
