PICKIT™ 2 PROGRAMMER-To-GO USER GUIDE The PICkit 2 Programmer-To-Go functionality allows a PIC MCU memory image To be downloaded inTo the PICkit 2 unit for later programming inTo a specific PIC MCU. No software or PC is required To program devices once the PICkit 2 unit is set up for Programming-To-Go. A USB power source for the PICkit 2 is all that is needed.

The PCA9541 is a 2-To-1 I2C-bus master selecTor designed for high reliability dual masterI2C-bus applications where system operation is required, even when one master fails orthe controller card is removed for maintenance. The two masters (for example, primaryand back-up) are located on separate I2C-buses that connect To the same downstreamI2C-bus slave devices. I2C-bus commands are sent by either I2C-bus master and are usedTo select one master at a time. Either master at any time can gain control of the slavedevices if the other master is disabled or removed from the system. The failed master isisolated from the system and will not affect communication between the on-line masterand the slave devices on the downstream I2C-bus.

The MAX3243E device consists of three line drivers, five line receivers, and a dual charge-pump circuit with±15-kV ESD (HBM and IEC61000-4-2, Air-Gap Discharge) and ±8-kV ESD (IEC61000-4-2, Contact Discharge)protection on serial-port connection pins. The device meets the requirements of TIA/EIA-232-F and provides theelectrical interface between an asynchronous communication controller and the serial-port connecTor. Thiscombination of drivers and receivers matches that needed for the typical serial port used in an IBM PC/AT, orcompatible. The charge pump and four small external capaciTors allow operation from a single 3-V To 5.5-Vsupply. In addition, the device includes an always-active noninverting output (ROUT2B), which allowsapplications using the ring indicaTor To transmit data while the device is powered down. The device operates atdata signaling rates up To 250 kbit/s and a maximum of 30-V/ms driver output slew rate.

Internal Interrupts are used To respond To asynchronous requests from a certain part of themicrocontroller that needs To be serviced. Each peripheral in the TriCore as well as theBus Control Unit, the Debug Unit, the Peripheral Control Processor (PCP) and the CPUitself can generate an Interrupt Request.So what is an external Interrupt?An external Interrupt is something alike as the internal Interrupt. The difference is that anexternal Interrupt request is caused by an external event. Normally this would be a pulseon Port0 or Port1, but it can be even a signal from the input buffer of the SSC, indicatingthat a service is requested.The User’s Manual does not explain this aspect in detail so this ApNote will explain themost common form of an external Interrupt request. This ApNote will show that there is aneasy way To react on a pulse on Port0 or Port1 and To create with this impulse an InterruptService Request. Later in the second part of the document, you can find hints on how Todebounce impulses To enable the use of a simple switch as the input device.Note: You will find additional information on how To setup the Interrupt System in theApNote “First steps through the TriCore Interrupt System” (AP3222xx)1. It would gobeyond the scope of this document To explain this here, but you will find selfexplanaToryexamples later on.

The PL2303 USB To Serial adapter is your smart and convenient accessory forconnecting RS-232 serial devices To your USB-equipped Windows host computer. Itprovides a bridge connection with a standard DB 9-pin male serial port connecTor inone end and a standard Type-A USB plug connecTor on the other end. You simplyattach the serial device onTo the serial port of the cable and plug the USB connecTorinTo your PC USB port. It allows a simple and easy way of adding serial connectionsTo your PC without having To go thru inserting a serial card and traditional portconfiguration.This USB To Serial adapter is ideal for connecting modems, cellular phones, PDAs,digital cameras, card readers and other serial devices To your computer. It providesserial connections up To 1Mbps of data transfer rate. And since USB does not requireany IRQ resource, more devices can be attached To the system without the previoushassles of device and resource conflicts.Finally, the PL-2303 USB To Serial adapter is a fully USB Specification compliantdevice and therefore supports advanced power management such as suspend andresume operations as well as remote wakeup. The PL-2303 USB Serial cable adapteris designed To work on all Windows operating systems.
