#175665 - because it is not there Responding to: ???'s previous message |
What is this crossbar ? I have seen it in the circuit diagrams
because it is not there. The crossbar is internal to the chip. Basically, if all I/O on the '120 was put out, there would be no general purpose pins left. The crossbar is a mechanism internal to the chip that only feed the peripherals you need (select) to port pins. see the F120 datasheet chapter 18 Erik |
