JTAGUID – JTAG User ID Register
MCUCR – MCU Control Register
ANAINIT: Analog Initialization
• Bit 3:0 – REVID[3:0]: MCU Revision ID
These bits contains the device revision. 0 = A, 1= B and so on.
• 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 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 or details refer to
• Bit 7:4 – 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 3:2 / 1:0 – STARTUPDLYx
Setting these bits enables sequential start of internal components used for the ADC, DAC, and
analog comparator with main input/output connected to that port. When this is done, the internal
components such as voltage reference and bias currents are started sequentially when the mod-
