Notes: 1. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses

should never be written.

2. 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.
