DEVID1 - MCU Device ID Register 1
DEVID2 - MCU Device ID Register 2
REVID - MCU Revision ID
JTAGUID – JTAG User ID Register
• Bit 7:0 - DEVID0[7:0]: MCU Device ID Byte 1
This byte will always be read as 0x1E. This indicates that the device is manufactured by Atmel
• Bit 7:0 - DEVID[7:0]: MCU Device ID Byte 1
Byte 1 of the device ID indicates the flash size of the device.
• Bit 7:0 - DEVID2[7:0]: MCU Device ID Byte 2
Byte 0 of the device ID indicates the device number.
• Bit 7:4 - Reserved
These bits are reserved and will always read as zero. For compatibility with future devices,
always write these bits to zero when this register is written.
• Bit 3:0 - REVID[3:0]: MCU Revision ID
These bits contains the device revision. 0=A, 1=B and so on.
