• Bit 7:3 - Reserved
These bits are reserved and will always be read as zero. For compatibility with future devices,
always write these bits to zero when this register is written.
• Bit 2 - AWEXELOCK: Advanced Waveform Extension Lock for TCE0
Setting this bit will lock all registers in the AWEXE module for Timer/Counter E0 for further mod-
ifications. This bit is protected by the Configuration Change Protection mechanism, for details
refer to
• Bit 1 - Reserved
This bit is reserved and will always be read as zero. For compatibility with future devices, always
write this bit to zero when this register is written.
• Bit 0 - AWEXCLOCK: Advanced Waveform Extension Lock for TCC0
Setting this bit will lock all registers in the AWEXC module for Timer/Counter C0 for further mod-
ifications. This bit is protected by the Configuration Change Protection mechanism, for details
