2.1
Programming Interfaces
All PIC32MX devices provide two physical interfaces to
the external programmer tool:
2-wire In-Circuit Serial Programming (ICSP)
4-wire Joint Test Action Group (JTAG)
more information.
Either of these methods may use a downloadable
Programming Executive (PE). The PE executes from
the target device RAM and hides device programming
details from the programmer. It also removes overhead
associated with data transfer and improves overall data
throughput. Microchip has developed a PE that is
available for use with any external programmer (see
more information).

2.2
Enhanced JTAG (EJTAG)
The 2-wire and 4-wire interfaces use the EJTAG proto-
col to exchange data with the programmer. While this
document provides a working description of this proto-
col as needed, advanced users are advised to refer to
the “EJTAG Specification
(www.mips.com).
2.3
Data Sizes
Per the EJTAG Specification, data sizes are defined as
follows:
One Word: 32 bits
One-half Word: 16 bits
One-quarter Word: 8 bits
One Byte: 8 bits
