7710F–AVR–09/11
EUSART Control Register B – EUCSRB
Table 19-2.
• Bit 7:5 –Reserved Bits
These bits are reserved for future use. For compatibilty with future devices, these bits must be
written to zero when EUSCRB is written.
• Bit 4 – EUSART Enable Bit
Set to enable the EUSART mode, clear to operate as standard USART.
• Bit 3– EUSBS Enable Bit
This bit selects the number of stop bits detected by the receiver.
Table 19-3.
Note:
• Bit 2–Reserved Bit
This bit is reserved for future use. For compatibilty with future devices, this bit must be written to
zero when EUSCRB is written.
