Description
Flash region lock bits. There is one bit per flash
region. A value of 1 means the region is
unlocked.
External privileged fetch lock. It is used to
prevent the CPU from fetching instructions from
external memories when in privileged mode. A
value of 1 means the external privileged fetch is
unlocked.
Used to set the size of the bootloader protected
area. See Table 6-2.
Be careful when setting these bits as reducing
the bootloader protected size will allow the
corruption or the destruction of the bootloader.
Note that a JTAGICE mkII is required to
reprogram the bootloader.
Brown-out detector trigger level. The higher the
value, the higher the BOD threshold level.
DO NOT ACTIVATE THE BOD WITH A
THRESHOLD ABOVE THE POWER SUPPLY
VOLTAGE OR THE PART WILL BECOME
UNUSABLE.
Enables the BOD hysteresis when at 1.
Hardware BOD enable state. See Table 6-3.
Tells the ISP to enable by software the BOD
when at 1. Not all values can be set when using
the ISP. See Table 6-3
When at 1, tells the boot process to use the ISP
configuration in the flash User page to determine
the I/O conditions to test to know which of the
USB DFU ISP and the application to start. See
Table 6-4.
Setting this bit to 0 allows the application to save
a GPIO pin and to free the last word of the User
page, but the ISP is then unreachable except if
the programmed application sets the
ISP_FORCE GP fuse bit to 1. This behavior can
be useful when extending Atmel’s bootloader
with an applicative bootloader (see Section
7.6.3.3).
When at 1, tells the boot process to start the
USB DFU ISP without testing any other
condition.
