1. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses
2. Some of the Status Flags are cleared by writing a logical “1” to them. Note that the CBI and SBI instructions will operate on
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 $00 to $1F only.
