Address
1. Refer to the USART description
2. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses
3. Some of the Status Flags are cleared by writing a logical one to them. Note that the CBI and SBI instructions will operate on
UBRRH/UCSRC Registers” on page
should never be written
all bits in the I/O Register, writing a one back into any flag read as set, thus clearing the flag. The CBI and SBI instructions
work with registers 0x00 to 0x1F only
