6.4
Long writes will not be supported on the PIC18C601/801
to program FLASH configuration memory. The configu-
ration locations can only be programmed in ICSP mode.
6.5
The Table Reads and Writes have the capability to
insert wait states when accessing external memory.
These wait states only apply to the execution of a Table
Read or Write to external memory and not to instruction
fetches out of external memory. The guidelines pre-
sented in Section 5.0 must be followed to select the
proper memory speed grade for the device operating
frequency.

The WAIT<1:0> bits in the MEMCON register will select
0, 1, 2, or 3 extra T
The wait will occur on Q4.
The default setting of the wait on power-up is to assert
a maximum wait of 3T
memories will work in Microprocessor mode immedi-
ately after RESET.
Figure 6-11 shows 8-bit external bus timing for a Table
Read with 2 wait cycles. Figure 6-12 shows 16-bit
external bus timing for a Table Read with 1 wait cycle.
