ATmega16(L)

Notes:

1. When the OCDEN Fuse is unprogrammed, the OSCCAL Register is always accessed on this address. Refer to the debug-

ger specific documentation for details on how to use the OCDR Register.

2. Refer to the USART description for details on how to access UBRRH and UCSRC.

3. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses

should never be written.

4. Some of the Status Flags are cleared by writing a logical one to them. Note that the CBI and SBI instructions will operate on

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 $00 to $1F only.
