PIC18F97J60 FAMILY
8.6.1
16-BIT BYTE WRITE MODE
Figure 8-1 shows an example of 16-Bit Byte Write
mode for PIC18F97J60 family 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
AD<15:0> bus. The appropriate WRH or WRL control
line is strobed on the LSb of the TBLPTR.
