See 

for details on using the 

ETM functionality.

The PINSEL5 register controls the functions of the pins as per the settings listed in 

. The direction control bit in the FIO2DIR register is effective only when the 

GPIO function is selected for a pin. For other functions, direction is controlled 
automatically.

The bit functions in this register depend on the number of pins of each LPC2400 part. For 
the 180-pin LPC2458, see 

. For the 208-pin LPC2460/68/70/78, see
