6.15 Modulation and Sampling Control SubSystem (MSCSS)
Table 21.
The LPC2939 each contain two I
The I
(SCL) and a serial data line (SDA). Each device is recognized by a unique address and
can operate as either a receiver-only device (e.g., an LCD driver) or as a transmitter with
the capability to both receive and send information (such as memory). Transmitters and/or
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 Modulation and Sampling Control Subsystem (MSCSS) in the LPC2939 includes four
Pulse-Width Modulators (PWMs), three 10-bit successive approximation Analog-to-Digital
Converters (ADCs) and two timers.

and do 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
