Chapter 9: LPC24XX Pin connect
5.5 Pin Function Select Register 4 (PINSEL4 - 0xE002 C010)
The PINSEL4 register controls the functions of the pins as per the settings listed in
Table 9–134
. 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 9–134
. For the 208-pin LPC2460/68/70/78, see
Table 9–135
. LCD functions are available in LPC2470/78 only and are selected in
Table 9–145
.
