User manual
The PINSEL registers control the functions of device pins as shown below. Pairs of bits in
these registers correspond to specific device pins.
Table 127. Pin function select register bits
The direction control bit in the GPIO registers is effective only when the GPIO function is
selected for a pin. For other functions, direction is controlled automatically. Each
derivative typically has a different pinout and therefore a different set of functions possible
for each pin. Details for a specific derivative may be found in the appropriate data sheet.
The PINMODE registers control the on-chip pull-up/pull-down resistor feature for all GPIO
ports. Two bits are used to control a port pin. PINMODEn register bits are reserved for not
available pins, e.g. pins P2[15:14] are not available on LPC2458 and are reserved in
PINSEL5 and PINMODE5.
Table 128. Pin Mode Select register bits
The Pin Control Module contains 12 registers as shown in
Remark: The LCD pins in the PINSEL registers are available on the LPC247x only.
