Lpc2000

Hi all,

I am using ARM LPC2106, I have following doubts about the 
configuration of PINSEL0 and PINSEL1.

1)where exactly should I define it in the initialsation?
 In common system initialisation or at the eac and every periphral 
(ex. UART0 or SPI etc.) initialisation.

2) suppose I want to use a single pin as multipurpose functioning, so 
how do I have to take care of PINSELn.
will it be always overwritten everytime or else we need to mask it 
and then modify it(for retaining its previous status).
