* Typical @ 25°C
[ 1 ] Ports P37-P34 may be used to sink 12 mA. These may be used
for LEDs or as general-purpose outputs requiring high sink
current.
[ 2 ] P00-P07, P10-P17, P20-P25, P30-P33 as output mode open-
drain as a logic one.
[ 3 ] P00-P07, P10-P17, P20-P25, P30-P33 as output mode open-
drain as a logic one.
