LPC2119/2129/2194/2292/2294ARM-based Microcontroller
Pin Function Select Register 2 (PINSEL2 - 0xE002C014)
The PINSEL2 register controls the functions of the pins as per the settings listed in Table 63. The direction control bit in the
IO1DIR register is effective only when the GPIO function is selected for a pin. For other functions direction is controlled
automatically.
Warning: use read-modify-write operation when accessing PINSEL2 register. Accidental write of 0 to bit 2 and/or bit 3 results in
loss of debug and/or trace functionality! Changing of either bit 4 or bit 5 from 1 to 0 may cause an incorrect code execution!
