Register Description – General Purpose I/O Memory
Register Descriptions – MCU Control
TEMPSENSE1 – Temperature Sensor Calibration Register 1
GPIORn – General Purpose I/O Register n
DEVID0 – Device ID Register 0
DEVID1 – Device ID Register 1
• Bit 7:0 – TEMPSENSE1[7:0]: Temperature Sensor Calibration Byte 1
This byte contains byte 1 of the temperature measurement.
These are general purpose register that can be used to store data such as global variables and
flags in the bit-accessible I/O memory space.
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]: 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]: Device ID Byte 1
Byte 1 of the device ID indicates the flash size of the device.
