4 SCC then, and 1 SMC for console. Both SMC1 and SMC2 I/Os are available
on the design (I only need serial ports + FEC ethernet).
I'd like to use 2 serial ports for RS232 (should be really
straightforward), and the other 2 for RS485 (with of course no flow
control). Is there something I should know ?
