PIC32MX3XX/4XX
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
programmer. ICSP is performed using a serial data
connection to the device and allows much faster pro-
gramming times than RTSP. RTSP techniques are
described in this chapter. The ICSP and EJTAG
methods are described in the “PIC32MX Flash
Programming Specification” (DS61145), which can be
downloaded from the Microchip web site.
Note:
PIC32MX3XX/4XX
Flash LVD Delay (LVDstartup) must be
taken into account between setting up and
executing any Flash command operation.
