/*
When the Brown-out Detector (BOD) is enabled by BODLEVEL fuses, Table 28-6 on page 293,
the BOD is actively monitoring the power supply voltage during a sleep period. To save power, it
is possible to disable the BOD by software for some of the sleep modes, see Table 10-1 on page
40. The sleep mode power consumption will then be at the same level as when BOD is globally
disabled by fuses. If BOD is disabled in software, the BOD function is turned off immediately
after entering the sleep mode. Upon wake-up from sleep, BOD is automatically enabled again.
This ensures safe operation in case the VCC level has dropped during the sleep period.
When the BOD has been disabled,the wake-up time from sleep mode will be approximately 60
µs to ensure that the BOD is working correctly before the MCU continues executing code.
BOD disable is controlled by bit 6, BODS (BOD Sleep) in the control register MCUCR, see
”MCUCR – MCU Control Register” on page 45. Writing this bit to one turns off the BOD in relevant
sleep modes, while a zero in this bit keeps BOD active. Default setting keeps BOD active,
i.e. BODS set to zero.

20.7.3 Receive Compete Flag and Interrupt
The USART Receiver has one flag that indicates the Receiver state.
The Receive Complete (RXCn) Flag indicates if there are unread data present in the receive
buffer. This flag is one when unread data exist in the receive buffer, and zero when the receive
buffer is empty (i.e., does not contain any unread data). If the Receiver is disabled (RXENn = 0),
the receive buffer will be flushed and consequently the RXCn bit will become zero.
When the Receive Complete Interrupt Enable (RXCIEn) in UCSRnB is set, the USART Receive
Complete interrupt will be executed as long as the RXCn Flag is set (provided thatglobal interrupts
are enabled). When interrupt-driven data reception is used, the receive complete routine
must read the received data from UDRn in order to clear the RXCn Flag, otherwise a new interrupt
will occur once the interrupt routine terminates.
