8.7.2 Description
8.7 Modulation and sampling control subsystem
The two LIN 2.0 master controllers in the LPC2917/19 have the pins listed below. The LIN
pins are combined with other functions on the port pins of the LPC2917/19.

The Modulation and Sampling Control Subsystem (MSCSS) in the LPC2917/19 includes
four Pulse-Width Modulators (PWMs), three10-bit successive approximation
Analog-to-Digital Converters (ADCs) and two timers.
The key features of the MSCSS are:
The MSCSS contains Pulse-Width Modulators (PWMs), Analog-to-Digital Converters
(ADCs) and timers.

communication with the AHB system bus. Two internal timers are dedicated to this
subsystem. MSCSS timer 0 can be used to generate start pulses for the ADCs and the
first PWM. The second timer (MSCSS timer 1) is used to generate ‘carrier’ signals for the
PWMs. These carrier patterns can be used, for example, in applications requiring current
