Hello Gus and Rodrigo,

Thanks for the answer, I was confused by the fact that the IO#PIN 
register is stated as a ReadOnly register on page 135 of the 
'UM_LPC21XX_LPC22XX_2.pdf'.

The conclusion is that IO#PIN isn't a ReadOnly register so the 
information on page 135 is wrong.

I am familiar with the Read Modify Write problem. In a 8051 circuit I 
had some jumpers on a port. Extreme caution was needed to prevent the 
use of ReadModifyWrite instructions.

I noticed the 'instanatneous', it is a copy and paste from the 
usermanual page 137.

Thanks again,
