7.2
In 16-bit mode, the external memory interface can be
connected to external memories in three different
configurations:
• 16-Bit Byte Write
• 16-Bit Word Write
• 16-Bit Byte Select
The configuration to be used is determined by the
WM1:WM0
(MEMCON<1:0>). These three different configurations
allow the designer maximum flexibility in using both
8-bit and 16-bit devices with 16-bit data.
For all 16-bit modes, the Address Latch Enable (ALE)
pin indicates that the address bits, A<15:0>, are avail-
able 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.
7.2.1
Figure 7-1 shows an example of 16-Bit Byte Write
mode for PIC18F8310/8410 devices. This mode is
used for two separate 8-bit memories connected for
16-bit operation. 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.
