6.14.3.1 Pin description
6.15.1 Functional description
6.15 Modulation and sampling control subsystem
receivers can operate in either master or slave mode, depending on whether the chip has
to initiate a data transfer or is only addressed. The I
controlled by more than one bus master connected to it.
The main features if the I

The Modulation and Sampling Control Subsystem (MSCSS) in the LPC2926/2927/2929
includes four Pulse Width Modulators (PWMs), three 10-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.

I
not support powering off of individual devices connected to the same bus lines.
Easy to configure as master, slave, or master/slave.
Programmable clocks allow versatile rate control.
Bidirectional data transfer between masters and slaves.
Multi-master bus (no central master).
Arbitration between simultaneously transmitting masters without corruption of serial
data on the bus.
Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus.
Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer.
