PIC32MZ Embedded Connectivity with Floating Point Unit (EF) Family
34.0 SPECIAL FEATURES
PIC32MZ EF devices include several features intended
to maximize application flexibility and reliability and
minimize cost through elimination of external
components. These are:
• Flexible device configuration
• Joint Test Action Group (JTAG) interface
• In-Circuit Serial Programming™ (ICSP™)
• Internal temperature sensor
34.1 Configuration Bits
PIC32MZ EF devices contain two Boot Flash memo-
ries (Boot Flash 1 and Boot Flash 2), each with an
associated configuration space. These configuration
spaces can be programmed to contain various
device configurations. Configuration space that is
aliased by the Lower Boot Alias memory region is
used to provide values for Configuration registers
listed below. See
4.1.1 “Boot Flash Sequence and
Configuration Spaces” for more information.
• DEVSIGN0/ADEVSIGN0: Device Signature Word
0 Register
• DEVCP0/ADEVCP0: Device Code-Protect 0
Register
• DEVCFG0/ADEVCFG0: Device Configuration
Word 0
• DEVCFG1/ADEVCFG1: Device Configuration
Word 1
• DEVCFG2/ADEVCFG2: Device Configuration
Word 2
• DEVCFG3/ADEVCFG3: Device Configuration

The following run-time programmable Configuration
registers provide additional configuration control:
• CFGCON: Configuration Control Register
• CFGEBIA: External Bus Interface Address Pin
Configuration Register
• CFGEBIC: External Bus Interface Control Pin
Configuration Register
• CFGPG: Permission Group Configuration
Register
In addition, the DEVID register (see Register 34-11)
provides device and revision information, and the
DEVSN0 and DEVSN1 registers contain a unique
serial number of the device (see
Register 34-12).
Note: This data sheet summarizes the features
of the PIC32MZ EF family of devices.
However, it is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to Section 32.
“Configuration” (DS60001124) and
Section 33. “Programming and
Diagnostics” (DS60001129) in the “PIC32
Family Reference Manual”
, which are
available from the Microchip web site
(www.microchip.com/PIC32).
Note: Do not use word program operation
(NVMOP<3:0>
= 0001) when
programming the device words that are
described in this section.
