Chapter 9: LPC24XX Pin connect
5.7 Pin Function Select Register 6 (PINSEL6 - 0xE002 C018)
The PINSEL6 register controls the functions of the pins as per the settings listed in
Table 9–138
. The direction control bit in the FIO3DIR register is effective only when the
GPIO function is selected for a pin. For other functions, direction is controlled
automatically.
[1] For flashless parts LPC2460/70, operates as BOOT0 pin on POR (see Section 8–6).
[2] For flashless parts LPC2460/70, operates as BOOT1 pin on POR (see Section 8–6
).
5.8 Pin Function Select Register 7 (PINSEL7 - 0xE002 C01C)
The PINSEL7 register controls the functions of the pins as per the settings listed in
Table 9–139
. The direction control bit in the FIO3DIR 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 9–139
. For the 208-pin LPC2460/68/70/78, see
Table 9–140
.
