CAN Controller 3 is available in LPC2294 only. Fields in the table related to CAN3 have Reserved

value for LPC2292.

6.9 Pin function select register 2 (PINSEL2 - 0xE002C014)

The PINSEL2 register controls the functions of the pins as per the settings listed in

Table 8. 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 the table are reserved, and should not be used.
