FLASH PROGRAM MEMORY
PIC32MX330/350/370/430/450/470 devices contain an
internal Flash program memory for executing user
code. There are three methods by which the user can
program this memory:
• Run-Time Self-Programming (RTSP)
• EJTAG Programming
• In-Circuit Serial Programming™ (ICSP™)
RTSP is performed by software executing from either
Flash or RAM memory. Information about RTSP
techniques is available in Section 5. “Flash Program
Memory” (DS60001121) in the “PIC32 Family
Reference Manual”.
EJTAG is performed using the EJTAG port of the
device and an EJTAG capable programmer.
ICSP is performed using a serial data connection to the
device and allows much faster programming times than
RTSP.
The EJTAG and ICSP methods are described in the
“PIC32 Flash Programming Specification”
(DS60001145), which can be downloaded from the
Microchip web site.
