18.2 Mask Values
The mask value of a device Configuration is calculated by setting all the unimplemented
bits to ‘0’ and all the implemented bits to ‘1’.
For example, Register 18-1 shows the DEVCFG0 register of the PIC32MX360F512L device. The
mask value for this register is as follows:
mask_value_devcfg0= 0x110FF00B
Table 18-1 lists the mask values of the four device
Configuration registers and device ID registers to be used in the checksum calculations
for the PIC32MX, PIC32MZ and PIC32MKXXXXGPD/GPE/MCFXXX devices.
PIC32MKXXXXGPK/MCM/GPG/MCJXXX devices use the CRC32 checksum. For additional information
on the CRC32 checksum, refer to the “Checksum Changes” chapter of the document “Readme
for MPLABX IDE.htm”, which can be found at <MPLABX Installation
Path>\<MPLABX Revision>\docs.
