• 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 further modifica-
tion. This bit is protected by the configuration change protection mechanism or details refer to
”Configuration Change Protection” on page
• 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 further modifica-
tion. This bit is protected by the configuration change protection mechanism or details refer to
