AT90S2313

0839I–AVR–06/02

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.
