#110574 - Maximum IOL per port pin: 10 mA ? Responding to: ???'s previous message |
Also the datasheet (in note 1) says,
Under steady state (non-transient) conditions, IOL must be externally limited as follows: 1) Maximum IOL per port pin: 10 mA 2) Maximum IOL per 8-bit port: Port 0: 26 mA . Ports 1, 2, 3: 15 mA Here i would like get cleared with point 1). It states max IOL per port pin = 10mA, which i find is not similar to any port pin (0 ,1, 2 or 3) IOL values. Doubt: Does that mean that p1.x could sink 10 mA when kept low. So, i would like to know what does this IOL = 10mA signify. Suggestions required. suresh. |
