• Manufacturer Part Number: AT90CAN128-16AE
• Description: 8-bit Avr Microcontroller With 128K Bytes of Isp Flash And CAN Controller.flash (Kbytes) 128 Vcc (V) 2.7-5.5 EEPROM (Kbytes) 4 SRAM (bytes) 4K CAN (mess. Obj.) 15
• Manufacturer: ATMEL Corporation

• Bit 15:12 – Reserved Bits
These bits are reserved for future use. For compatibility with future devices, these bit
must be written to zero when UBRRnH is written.
• Bit 11:0 – UBRRn11:0: USARTn Baud Rate Register
This is a 12-bit register which contains the USARTn baud rate. The UBRRnH contains
the four most significant bits, and the UBRRnL contains the eight least significant bits of
the USARTn baud rate. Ongoing transmissions by the Transmitter and Receiver will be
corrupted if the baud rate is changed. Writing UBRRnL will trigger an immediate update
of the baud rate prescaler.
