Hello all, This isn't actually a question about the 683xx, but for the HCS12DP256. Some I/O pins have the capability of full (10ma) drive and 1/3 drive settings. What is the reliability of the processor if I drive a full drive pin to VCC and connect it via a (approx) 50 ohm resistor to an other pin driven low with 1/3 drive? This contention would last for ~ 200 microseconds out of a period of 40 milliseconds. 0.5% duty cycle effectively. Basically like an active pull down. or please point me in the correct direction.
