This programming specification is designed to guide developers of external programmer tools. Customers who are developing applications for PIC32 devices should use development tools that already provide support for device programming. The major topics of discussion include: • Section 1.0 “Device Overview” • Section 2.0 “Programming Overview” • Section 3.0 “Programming Steps” • Section 4.0 “Connecting to the Device” • Section 5.0 “EJTAG vs. ICSP” • Section 6.0 “Pseudo Operations” • Section 7.0 “Entering 2-Wire Enhanced ICSP Mode” • Section 8.0 “Check Device Status” • Section 9.0 “Erasing the Device” • Section 10.0 “Entering Serial Execution Mode” • Section 11.0 “Downloading the Programming Executive (PE)” • Section 12.0 “Downloading a Data Block” • Section 13.0 “Initiating a Flash Row Write” • Section 14.0 “Verify Device Memory” • Section 15.0 “Exiting Programming Mode” • Section 16.0 “The Programming Executive” • Section 17.0 “Checksum” • Section 18.0 “Configuration Memory and Device ID” • Section 19.0 “TAP Controllers” • Section 20.0 “AC/DC Characteristics and Timing Requirements” • Appendix A: “PIC32 Flash Memory Map” • Appendix B: “Hex File Format” • Appendix C: “Revision History” 2.0 PROGRAMMING OVERVIEW All PIC32 devices can be programmed through two primary methods: • Self-programming • External tool programming The self-programming method requires that the target device already contains executable code with the logic necessary to complete the programming sequence. The external tool programming method does not require any code in the target device – it can program all target devices with or without any executable code. This document describes the external tool programming method. Refer to the individual sections of the “PIC32 Family Reference Manual” and the specific device data sheet for more information about using the self-programming method. An external tool programming setup consists of an external programmer tool and a target PIC32 device. Figure 2-1 illustrates the block diagram view of the typical programming setup. The programmer tool is responsible for executing necessary programming steps and completing the programming operation. FIGURE 2-1: PROGRAMMING SYSTEM SETUP 2.1 Devices with Dual Flash Panel and Dual Boot Regions The PIC32MZ Embedded Connectivity (EC) family of devices incorporate several features useful for field (self) programming of the device. These features include dual Flash panels with dual Boot regions, an aliasing scheme for the Boot regions allowing auto- matic selection of Boot code at start-up and a panel swap feature for program Flash. The two Flash panels and their associated Boot regions can be erased and programmed separately. Refer to Section 3. “Memory Organization” (DS61115) in the “PIC32 Family Reference Manual” for a detailed explanation of these features. A development tool used for production programming will not be concerned about most of these features with the following exceptions: • Insuring that the SWAP bit (NVMCON<7>) is in the proper setting. The default setting is ‘ 0’ for no swap of panels. The development tool should assume the default setting when generating source files for the programming tool. • Proper handling of the aliasing of the Boot memory in the checksum calculation. The aliased sections will be duplicates of the fixed sections. See Section 17.0 “Checksum” for more information on checksum calculations with aliased regions.
