FUSEBYTE5 - Non-Volatile Memory Fuse Byte 5
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 this fuse is programmed the
ENABLE bit in the watchdog CTRL register is automatically set at reset. The WEN bit in the
watchdog WINCTRL register is not set automatically and needs to be enabled from software.
Table 4-4.
• Bit 0 - JTAGEN: JTAG enabled
The JTAGEN fuse decides whether or not the JTAG interface is enabled.
When the JTAG interface is disabled all access through JTAG is prohibited, and the device can
only be accessed using the Program and Debug Interface (PDI).
Table 4-5.
The JTAGEN fuse is only available on devices with JTAG interface.
• Bit 7:6 - Reserved
These bits are reserved. For compatibility with future devices, always write these bits to one
when this register is written.
