Register Descriptions – MCU Control
DEVID0 – MCU Device ID Register 0
DEVID1 – MCU Device ID Register 1
DEVID2 – MCU Device ID Register 2
REVID – MCU Revision ID
DEVID0, DEVID1 and DEVID2 contain the -byte identification that identif each microcontroller
device type. For details on the actual ID, refer to the device datasheet.
• Bit 7:0 – DEVID0[7:0]: MCU Device ID Byte 0
Byte 0 of the device ID. 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 2 of the device ID indicates the device number.
• Bit 7:4 – Reserved
These bits are reserved and will always read as zero.
