The PIC18F8525/8622 External Memory Bus (EMB)
can be activated during In-Circuit Serial Program-
ming™ (ICSP™) to program external Flash memory
devices. The EMB is always disabled upon Program
mode entry. TCFG3L, located at address 380004h, is a
special register available in ICSP which overrides
CONFIG3L.
The code sequence to enable the EMB for Byte Write
mode, with 0 wait counts during ICSP, is shown in
Table 3-10.
