6.10.1
Features
Direction control of individual bits.
Separate control of output set and clear.
All I/O default to inputs after reset.
6.11 10-bit A/D converter
The LPC2290 contains single 10-bit successive approximation analog to digital
converter with eight multiplexed channels.
6.11.1
Features
Measurement range of 0 V to 3 V.
Capable of performing more than 400,000 10-bit samples per second.
Burst conversion mode for single or multiple inputs.
Optional conversion on transition on input pin or Timer Match signal.
6.12 CAN controllers and acceptance filter
The LPC2290 contains two CAN controllers. The Controller Area network (CAN) is a
serial communications protocol which efficiently supports distributed real-time control
with a very high level of security. Its domain of application ranges from high speed
networks to low cost multiplex wiring.
6.12.1
Features
Data rates up to 1 Mbit/s on each bus.
32-bit register and RAM access.
Compatible with CAN specification 2.0B, ISO 11898-1.
Global Acceptance Filter recognizes 11 and 29-bit Rx identifiers for all CAN buses.
Acceptance Filter can provide FullCAN-style automatic reception for selected
Standard identifiers.
6.13 UARTs
The LPC2290 contains two UARTs. One UART provides a full modem control
handshake interface, the other provides only transmit and receive data lines.
6.13.1
Features
16 byte Receive and Transmit FIFOs.
Register locations conform to ‘550 industry standard.
Receiver FIFO trigger points at 1, 4, 8, and 14 bytes
Built-in baud rate generator.
Standard modem interface signals included on UART1.
