Chapter 9: LPC24XX Pin connect
[1] See Section 9–5.11 “Pin Function Select Register 10 (PINSEL10 - 0xE002 C028)” for details on using the
ETM functionality.
5.6 Pin Function Select Register 5 (PINSEL5 - 0xE002 C014)
The PINSEL5 register controls the functions of the pins as per the settings listed in
Table 9–136 . 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
Table 9–136 . For the 208-pin LPC2460/68/70/78, see
Table 9–137 .
