Available on LPC2104/2105/2106/01 only.
6.6 Pin connect block
The pin connect block allows selected pins of the microcontroller to have more than one
function. Conguration registers control the multiplexers to allow connection between the
pin and the on chip peripherals. Peripherals should be connected to the appropriate pins
prior to being activated, and prior to any related interrupt(s) being enabled. Activity of any
enabled peripheral function that is not mapped to a related pin should be considered
undened.
The Pin Control Module contains two registers as shown in Table 5.
6.7 Pin function select register 0 (PINSEL0 - 0xE002 C000)
The PINSEL0 register controls the functions of the pins as per the settings listed in
Table 6. The direction control bit in the IODIR register is effective only when the GPIO
function is selected for a pin. For other functions, direction is controlled automatically.
Settings other than those shown in Table 6 are reserved, and should not be used
