Chapter 9: LPC24XX Pin connect
5.9 Pin Function Select Register 8 (PINSEL8 - 0xE002 C020)
The PINSEL8 register controls the functions of the pins as per the settings listed in
Table 9–141 . The direction control bit in the FIO4DIR register is effective only when the
GPIO function is selected for a pin. For other functions, direction is controlled
automatically.
