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
“
1
”
to them. Note that the CBI and SBI instructions will operate on all
bits in the I/O register, writing a
“
1
”
back into any flag read as set, thus clearing the flag. The CBI and SBI instructions work
with registers $00 to $1F only.
