Program Memory Write/Erase
Requirements
The Flash program memory on the PIC24FJXXXGA0XX
devices has a specific write/erase requirement that must
be adhered to for proper device operation. The rule is
that any given word in memory must not be written more
than twice before erasing the page in which it is located.
Thus, the easiest way to conform to this rule is to write
all the data in a programming block within one write
cycle. The programming methods specified in this
specification comply with this requirement.
2.3
Pin Diagrams
The pin diagrams for the PIC24FJXXXGA0XX family
are shown in the following figures. The pins that are
required for programming are listed in Table 2-1 and
are shown in bold letters in the figures. Refer to the
appropriate device data sheet for complete pin
descriptions.
TABLE 2-1:
PIN DESCRIPTIONS (DURING PROGRAMMING)
Note:
Writing to a location multiple times without
erasing is not recommended.
