8.4
When the table reads/writes are accessing external
memory (via the external system interface bus), the
table latch for the table reads is different from the table
latch for the table writes (see Figure 8-9).
This means that you cannot do a TABLRD instruction,
and use the values that were loaded into the table
latches for a TABLWT instruction. Any table write
sequence should use both the TLWT and then the
TABLWT instructions.
