FUSEBYTE4 - Non-Volatile Memory fuse Byte4 - Start-up Configuration
• Bit 1:0 - BODPD[1:0]: BOD operation in power-down mode
The BODPD fuse bits set the BOD operation mode in all sleep modes except Idle mode.
For details on the BOD and BOD operation modes refer to
Table 4-2.
• Bit 7:5 - Reserved
These fuse bits are reserved. For compatibility with future devices, always write these bits to one
when this register is written.
• Bit: 4 - RSTDISBL - External Reset Disable
This fuse can be programmed to disable the external reset pin functionality. When this is done
pulling this pin low will not cause an external reset.
• Bit 3:2 - STARTUPTIME[1:0]: Start-up time
The STARTUPTIME fuse bits can be used to set at a programmable timeout period from all
reset sources are released and until the internal reset is released from the delay counter.
The delay is timed from the 1kHz output of the ULP oscillator, refer to
Sequence” on page 104
Table 4-3.
• Bit 1 - WDLOCK: Watchdog Timer lock
The WDLOCK fuse can be programmed to lock the Watchdog Timer configuration. When this
fuse is programmed the Watchdog Timer configuration cannot be changed, and the Watchdog
Timer cannot be disabled from the application software. When the WDLOCK fuse is pro-
grammed the the watchdog timer is automatically enabled at reset.
