LPC2921/2923/2925

ARM9 microcontroller with CAN, LIN, and USB

6.14.2 Pin description

The pins of the LPC2921/2923/2925 MSCSS associated with the two ADC modules are

described in Section 6.14.4.2. Pins connected to the four PWM modules are described in

Section 6.14.5.4, pins directly connected to the MSCSS timer 1 module are described in

Section 6.14.6.1, and pins connected to the quadrature encoder interface are described in

Section 6.14.7.1.
