7.0 FLASH PROGRAM MEMORY
Note:
This data sheet summarizes the features of
the PIC32MX3XX/4XX family of devices. It
is not intended to be a comprehensive refer-
ence source. Refer to the “PIC32MX Family
Reference Manual” (DS61132) for a
detailed description of this peripheral.
The PIC32MX3XX/4XX of devices contain internal pro-
gram Flash memory for executing user code. There are
three methods by which the user can program this
memory:
1. Run-Time Self Programming (RTSP)
2. In-Circuit Serial Programming™ (ICSP™)
3. 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) document, which may
be downloaded from the Microchip web site.
