ST7-EMU3 series emulator

34/39

PC (Program counter)

The CPU register that holds the address of the next instruction or operand that the

CPU will use.

PLD (Programmable logic device)

An integrated circuit that can be programmed to perform complex functions.

PQFP (Plastic quad flat package)

A family of integrated circuit packages for surface mounted assembly. This type is

packaged with plastic, has a square flat shape and pins on all four sides.

RC network (Resistor-capacitor network)

A combination of resistors and capacitors in a circuit that are typically used to control or

minimize voltage spikes.

Read/Write on the fly

A feature that allows you to perform a non-intrusive read or write of a variable during

emulation (i.e. while program running). The variable may be 8, 16 or 32 bits in size and

can be located anywhere in the emulation memory (up to 64 kilobytes) except for the

hardware register (peripherals) and internal system (A, X, Y, PC, CC and SP). The

Read/Write on the fly option is available in both the Memory window and Watch window

of STVD7.

SDIP (Shrink dual in-line package)

A type of device package with two rows of pins for thru-hole mounting.

SO (Small outline)

A type of device package with two rows of pins for SMD or socket mounting.

STVD7 (ST7 visual develop)

A software package that allows you to debug applications destined for the ST7 family of

MCUs, either using a built-in simulator function, a development or an emulator.

STVP7 (ST7 visual programmer)

A software application that allows you to program ICC-enabled microcontrollers using

an ICC link for an emulator or a development.

Target device

The ST7 devices that you have chosen for your application microcontroller and that you

will emulate or program.

TEB (Target emulation board)

A target emulation board for the EMU3 series of emulators. A printed board having

connector pins that, when plugged into the dedicated emulation board (DEB) of the

EMU3 probe, allows you to connect the EMU3 probe to the MCU socket of the user

application board.
