Lpc2000

Hi, I'm studying LPC2214 for use on a new project. I have some doubts and I think someone could help me in this forum.
 
1) I need to control 3 step motors. They are completely independent. In the Philips LPC User Manual, they say it's better use channels 2, 4 and 6 for double edge. It's not clear to me how can I make one motor accelerate while another one is in it maximum speed i. e. how can I maintain their independency.
 
2) If I use PWM channels 2, 4 and 6 I can't use UART1(PWM6 and UART1 use the same pin)... Is that correct?
 
 
Thanks
 
Andre
