5.0 FLASH PROGRAM MEMORY
Note 1: This data sheet summarizes the features
of the PIC32MX3XX/4XX family of
devices. It is not intended to be a compre-
hensive reference source. To comple-
ment the information in this data sheet,
refer to Section 5. “Flash Program
Memory” (DS61121) of the “PIC32MX
Family Reference Manual”, which is avail-
able from the Microchip web site
(www.microchip.com/PIC32).
2: Some registers and associated bits
described in this section may not be avail-
able on all devices. Refer to Section 4.0
“Memory Organization” in this data
sheet for device-specific register and bit
information.
PIC32MX3XX/4XX
PIC32MX3XX/4XX devices contain an internal
program Flash memory for executing user code. There
are three methods by which the user can program this
memory:
• Run-Time Self Programming (RTSP)
• In-Circuit Serial Programming™ (ICSP™)
• EJTAG Programming
RTSP is performed by software executing from either
Flash or RAM memory. EJTAG is performed using the
EJTAG port of the device and a EJTAG capable pro-
grammer. ICSP is performed using a serial data con-
nection to the device and allows much faster
programming times than RTSP. RTSP techniques are
described in this chapter. The ICSP and EJTAG meth-
ods are described in the “PIC32MX3XX/4XX Program-
ming Specification” (DS61145), which may be
downloaded from the Microchip web site.
