3.1.2
When using low-voltage ICSP, the part must be
supplied by the voltage specified in Parameter D111 if
a Bulk Erase is to be executed. All other Bulk Erase
details, as described above, apply.
If it is determined that a program memory erase must
be performed at a supply voltage below the Bulk Erase
limit, refer to the erase methodology described in
Section 3.1.3 “ICSP Row Erase”
“Modifying Code
FIGURE 3-2:
3.1.3
Regardless of whether high or low-voltage ICSP is used,
it is possible to erase one row (64 bytes of data), provided
the block is not code or write-protected. Rows are located
at static boundaries, beginning at program memory
address, 000000h, extending to the internal program
memory limit (see
The Row Erase duration is externally timed and is
controlled by PGC. After the WR bit in EECON1 is set,
a NOP is issued, where the 4th PGC is held high for the
duration of the programming time, P9.
After PGC is brought low, the programming sequence
is terminated. PGC must be held low for the time
specified by Parameter P10 to allow high-voltage
discharge of the memory array.
