to continue operating if VDD falls below 2.85 V. However, it will not be able to power up successfully
from a voltage below 2.85 V, because SBOREN is set to 1 on power-up. Also, the microcontroller is
not guaranteed to operate correctly below 2.7 V without switching to a slower clock source.
Watchdog timer
The watchdog timer is disabled by default, but it can be enabled by setting the SWDTEN bit in the
WDTCON register. The watchdog postscaler is set to 1:256, so the watchdog timer’s period is about
1048 ms.
Read/write protection
The region of flash memory occupied by the bootloader is write-protected to prevent accidental
corruption of the bootloader. The lower 2 KB of the bootloader’s flash memory are readable and
contain some useful data (as described in
Section 6.1 ), but the rest of the bootloader is read-
protected.
