2.2
Program Memory Write/Erase
Requirements
The program Flash memory on the dsPIC33F/PIC24H
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 without
first 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 document
comply with this requirement.
2.3
Pins Used During Programming
The pins that are used for programming are listed in
TABLE 2-1:
PINS USED DURING PROGRAMMING
Note 1: These are typical operating voltages. Refer
operating ranges of VDD and VCAP.
2: It is important for the low-ESR capacitor to
be placed as close as possible to the VCAP
pin.

Note:
A program memory word can be
programmed twice before an erase, but
only if (a) the same data is used in both
program operations or (b) bits containing
‘1’ are set to ‘0’ but no ‘0’ is set to ‘1’.
Note:
Refer to the specific device data sheet for
complete pin diagrams of the dsPIC33F/
PIC24H devices.
