Table 11-4 shows the ICSP programming process for
bulk-erasing program memory. This process includes
the ICSP command code, which must be transmitted
(for each instruction) to the Least Significant bit first
using the PGC and PGD pins (see Figure 11-2).
If an individual Segment Erase operation is required,
the NVMCON value must be replaced by the value for
Note:
Program memory must be erased before
writing any data to program memory.
the corresponding Segment Erase operation.
