The flash block contains 32 general purpose fuses. These 32 fuses can be found in the Flash
General Purpose Fuse Register Low. Some of these fuses have defined meanings outside the
flash controller and are described in this section.
In addition to the General Purpose fuses parts of the Flash, user page can have a defined mean-
ing outside the flash controller and are described in this section. Note that after writing the user
page, values will not be propagated to other modules internally on the device. Other modules
will load these values after resetting the chip.
The general purpose fuses are erased by a JTAG or aWire chip erase.
