8.7.3MSCSS pin description

The pins of the LPC2917/19 MSCSS associated with the two ADC modules are described in Section 8.7.5.3. Pins directly connected to the four PWM modules are described in Section 8.7.6.5: pins directly connected to the MSCSS timer 1 module are described in Section 8.7.7.3.

8.7.4MSCSS clock description

The MSCSS is clocked from a number of different sources:
