MCUCR – MCU Control Register
EVSYSLOCK – Event System Lock Register
• Bit 7:0 - JTAGUID[7:0]: JTAG User ID
The JTAGUID can be used to identify two devices with identical Device ID in a JTAG scan chain.
The JTAGUID will during reset automatically be loaded from flash and placed in these registers.
• 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 - JTAGD: JTAG Disable
Setting this bit will disable the JTAG interface. This bit is protected by the Configuration Change
Protection mechanism, for details refer to
page
• Bit 7:5 - 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 4 - EVSYS1LOCK:
Setting this bit will lock all registers in the Event System related to event channels 4 to 7 for fur-
ther modifications. The following registers in the Event System are locked: CH4MUX,
CH4CTRL, CH5MUX, CH5CTRL, CH6MUX, CH6CTRL, CH7MUX, CH7CTRL. This bit is pro-
tected by the Configuration Change Protection mechanism, for details refer to
”Configuration Change Protection” on page
• Bit 3:1 - 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:
Setting this bit will lock all registers in the Event System related to event channels 0 to 3 for fur-
ther modifications. The following registers in the Event System are locked: CH0MUX,
CH0CTRL, CH1MUX, CH1CTRL, CH2MUX, CH2CTRL, CH3MUX, CH3CTRL. This bit is pro-
