LPC2114/2124 pin select usage

2005-03-31 by bobtransformer

I have been excited about trying the LPC2114 and LPC2124 parts (and 
similar parts) and notice in the users manual that when certain pins 
are assigned certain functions, other pins cannot be used for general 
IO etc.

I am used to Microchip and AVR type parts where any pin can pretty 
much be assigned to be used as general IO or the alternate dedicated  
pin functions (TXD, RXD, PWM, cap, int, etc.)

Is it really true that these parts have this limited pin usage ?
For instance, it looks like I cannot use UART0 and UART1 and still 
use PWM outputs 2 and 5 even though neither function shares pins.

I also see a lot of "reserved" pins when certain pin functions are 
assigned that would waste otherwise useful IO.  This would severely 
limit usage of these parts.

This can't be true, can it ? 
thanks,
bob
