CONNECTOR DESCRIPTIONS JTAG: The JTAG connector allows the software debugger to talk via a JTAG (Joint Test Action Group) port directly to the core. Instructions may be inserted and executed by the core thus allowing LPC2148 memory to be programmed with code and executed step by step by the host software. For more details refer to IEEE Standard 1149.1 - 1990 Standard Test Access Port and Boundary Scan Architecture and LPC2148 datasheets and users manual.

I2C The I2C-bus is bidirectional, for inter-IC control using only two wires: a serial clock line (SCL), and a serial data line (SDA). Each device is recognized by a unique address and can operate as either a receiver-only device. 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 I2C-bus is a multi-master bus, it can be controlled by more than one bus master connected to it. The I2C-bus implemented in LPC2148 supports bit rates up to 400 kbit/s (Fast I2C-bus).

Features: – – – – – – – – –

Compliant with standard I2C-bus interface. 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. The I2C-bus can be used for test and diagnostic purposes.

SPI The SPI is a full duplex serial interface, designed to handle multiple masters and slaves connected to a given bus. Only a single master and a single slave can communicate on the interface during a given data transfer. During a data transfer the master always sends a byte of data to the slave, and the slave always sends a byte of data to the master.

Features: – – – –

Compliant with SPI specification. Synchronous, Serial, Full Duplex, Communication. Combined SPI master and slave. Maximum data bit rate of one eighth of the input clock rate.
