MCUCR – MCU Control Register
EVSYSLOCK – Event System Lock Register
AWEXLOCK – Advanced Waveform Extension Lock Register
• Bit 7:0 - 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 7:1 - 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 0 - EVSYS0LOCK:
Writing this bit to one will lock all registers in the Event System related to event channels 0 to 3
for further modifications. The following registers in the Event System are locked: CH0MUX,
CH0CTRL, CH1MUX, CH1CTRL, CH2MUX, CH2CTRL, CH3MUX, CH3CTRL. This bit is pro-
tected by the Configuration Change Protection mechanism, for details refer to
”Configuration Change Protection” on page
• Bit 7:1 - 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 0 - AWEXCLOCK: Advanced Waveform Extension Lock for TCC0
Writing this bit to one will lock all registers in the AWEXC module for Timer/Counter C0 for fur-
ther modifications. This bit is protected by the Configuration Change Protection mechanism, for
details refer to
