NOTES:
1. V
DD
, OPT
X
, and V
DDQX
must be set to appropriate operating levels prior to
applying inputs on I/O
X
.
2. OPT
X
selects the operating voltage levels for the I/Os and controls on that port.
If OPT
X
is set to V
DD
(2.5V), then that port's I/Os and controls will operate at 3.3V
levels and V
DDQX
must be supplied at 3.3V. If OPT
X
is set to V
SS
(0V), then that
port's I/Os and controls will operate at 2.5V levels and V
DDQX
must be supplied
at 2.5V. The OPT pins are independent of one another—both ports can operate
at 3.3V levels, both can operate at 2.5V levels, or either can operate at 3.3V
with the other at 2.5V.
3. The sleep mode pin shuts off all dynamic inputs, except JTAG inputs, when
asserted. OPTx,
INT
x and the sleep mode pins themselves (ZZx) are not
affected during sleep mode. It is recommended that boundry scan not be operated
during sleep mode.
