7.10 I
7.8 10-bit ADC
7.9 UARTs
The MPT612 contains one Analog-to-Digital Converter (ADC). It is a single 10-bit
successive approximation ADC with eight channels, three of which are used internally.
The ADC provides the following features:
The MPT612 contain two UARTs. In addition to standard transmit and receive data lines
UART1 also provides a full modem control handshake interface. The UARTs in MPT612
include a fractional baud rate generator for both UARTs. Standard baud rates such as
115200 can be achieved with any crystal frequency above 2 MHz. The UARTs provide
the following features:
The MPT612 contains two I
The I
the Serial DAta line (SDA). Each I
can operate as either a receiver-only device (e.g., LCD driver) or a transmitter with the
capability to both receive and send information such as serial 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

C-bus). The controller provides the following features:
C-bus serial I/O controllers
• Separate control of output set and clear
• All I/O default to inputs after reset
• Measurement range from 0 V to 3.3 V
• The converter can perform more than 400 000 10-bit samples per second
• Burst conversion mode for single or multiple inputs
• Optional conversion on input pin transition or Timer Match signal
• Every analog input has a dedicated result register to reduce interrupt overhead
• 16-byte receive and transmit FIFOs
• Register locations conform to 16C550 industry standard
• Receiver FIFO trigger points at 1-byte, 4-byte, 8-byte and 14-byte
• Built-in fractional baud rate generator covering wide range of baud rates without a
