AWEXLOCK – Advanced Waveform Extension Lock Register
• Bit 7:1 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits 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-
ification. This bit is protected by the configuration change protection mechanism or details refer
