1.1 OVERVIEW

This chapter provides an overview of the Motorola M68ICS08AB in-circuit simulator (ABICS) and a quick start guide to setting up a development project.
The ABICS board, a 107 ´ 109-mm PCB (printed circuit board), is a stand­alone development and debugging aid for designers using MC68HC908AB32 microcontroller unit (MCU) devices. The ABICS contains both the hardware (the M68ICS08AB) and software (ICD08SZã) needed to develop and simulate source code for, and to program, Motorola’s MC68HC908AB32 microcontrollers. Refer to the M68ICS08AB IN-CIRCUIT SIMULATOR SOFTW ARE OPERATOR’S MANUAL for detailed information about the ICD08SZ software.
The ABICS and the ICS08AB software form a complete simulator and limited real-time I/O (input/output) emulator for the MC68HC908AB32 MCU devices. When the ABICS is connected to a host PC and target hardware, the actual inputs and outputs of the target system can be used during simulation of code.
CHAPTER 1

INTRODUCTION

The ABICS connects to the target machine via a Motorola M68CLB05C FLEX cable. It connects to the software host via a single RS-232 connection and a standard DB-9 serial cable.
Use the ABICS with any IBM Windows 3.x-, Windows 95-, or Windows 98­based computer with a serial port.

1.3 ABICS INTERFACE MODULE OVERVIEW

The ABICS includes a single 107 x 109-mm printed circuit board (PCB) (M68ICS08AB). Figure 1-1 shows a diagram of the ABICS board. For an enlarged view of this board, refer to Section A.8 BOARD LAYOUT AND SCHEMATIC DIAGRAMS.
Figure 1-1. ABICS Board Layout

1.3.1 Board Interface Connectors

The development system interface is via the single system connector P2, which is a 9-pin, D-type, through-hole, female, right angle connector (Amp part number AMP-9726-A) mounted on the top side of the PCB.
The ABICS user target interface is via the target header connector J1, J2, two 40-pin shrouded headers. J1, J2 are positioned to easily interface to a Motorola M68CLB05C FLEX cable. The FLEX cable connects to the host system through the appropriate target head adapter.
The ABICS board uses two supply voltages:
• Self-tracked +3.0-volt to +5.0-volt regulator supply for the ABICS and
level translation devices
• A +5-V supply for the remainder of the logic
The interface to the host development system uses +5-V TTL (transistor-to­transistor logic) signaling levels. The interface to the target system uses signaling levels based on the user-selected supply.

1.3.2 MCU Subsystem

The MCU subsystem consists of the MC68HC908AB32 microcontroller,clock generation , monitor mode control logic that places and holds the ABICS in monitor mode, the bus voltage level translation buffers, and processor operating voltage variable regulator.
1.3.2.1 Block Diagram of Simulator Board
Figure 1-3 shows a block diagram of the ABICS simulator board. The individual blocks are described in the subsections following the diagram.
Figure 1-3. MC68HC908AB32 In-Circuit Simulator Block Diagram
1-6 M68ICS08ABUM/D
1.3.2.2 M68HC908AB32 MCU
The MCU is an MC68HC908AB32 and is available in one package only:
• 64-pin QFP
The QFP package mounts in a clam-shell socket. The on-board MCU (the test MCU) simulates and debugs the MCU’s interface
to its peripherals and to other devices on the target board through a variety of connections. Depending on the connection, the MCU is used in one of three operating modes:
• In the ICS socket for programming and simple simulation
• In the socket and connected to the target for emulation
• On the target for MON08 debug operation
1.3.2.3 Clocks
CHAPTER 1 – INTRODUCTION
The ABICS contains a 4.1952-MHz crystal oscillator. When the remote target connection is made, the user may opt to feed the output from the ABICS crystal (SP-OSC) to the external clock input (OSC1) of the ABICS via W5, a 2-pin shunt.
1.3.2.4 Board Reset
The ABICS includes two reset sources:
• An output from the POR (Power-On Reset) circuit via the host system
software
• An internal reset exception operation of the processor
The host system resets the ICS by cycling power to most of the ICS circuitry, including the POR circuit. RS-232 handshake line DTR is used for this purpose.
The RESET function of the ABICS is both an input and an output. The ABICS drives its RESET pin low after encountering several different exception conditions. W3 is providedto allowyou to select whether the target system can reset the MCU on the ABICS (jumper between pins 1 and 2) or whether the target system receives a reset signal from the ABICS (jumper between pins 2 and 3).
M68ICS08ABUM/D 1-7
CHAPTER 1 – INTRODUCTION
RST* is not a bidirectional, open-drain signal at the target connectors. Removing the jumper leaves the RST-IN* signal pulled up to MCU operating voltage.
1.3.2.5 Device Configuration Selection
The operation mode of the ABICS processor is selected at the rising edge of the RESET signal. The ABICS requires that the processor operate in monitor mode. To set monitor mode operation, the IRQ* line to the ABICS is level shiftedtoapplyVHIto the processor on the rising edge of reset. The VHIis a signal name that is specified as minimum VDD+ 2.5 V and maximum 9 V, with the highest VDDof 3.3 V, which gives a range of minimum 5.8 V and maximum 9 V.
The ABICS RST* pin is the main mode select input and is pulled to logic 0, then logic 1 (processor VDD), to select MCU monitor mode. The host software must communicate security bytes to the MCU to resume execution out of reset. Communication to the monitor ROM is via standard, non-return-to-zero (NRZ) mark/space data format on PTA0. The MCU maintains monitor mode and disables the COP module through continued application of VHIon either IRQ* or RST*.
Six commands may be issued by the host software in control of the MCU in monitor mode: read, write, iread, iwrite, readsp,andrun. Each command is echoed back through PTA0 for error checking. These commands are described in the M68ICS08AB IN-CIRCUIT SIMULATOR SOFTWARE
OPERATOR’S MANUAL.
The MCU bus clock is CGMXCLK/2.
1.3.2.6 Level Translation
The ABICS has an operation voltage range of +3.0 to +5.0 volts while the host developmentsystem interface is an RS-232 (com) port. U2 on the ICS converts 5 V logic signals to RS-232 levels. Transistors Q9-Q10 translate 5 V logic levels to the MCU operating voltage (3.0-5.0 V).
1-8 M68ICS08ABUM/D
1.3.2.7 ABICS Operating Voltage, Variable Selector
To provide the ABICS with power input that matches your target environment, the ABICS includes a on-board regulator. The ABICS monitors the user’s target system power via the EVDD pin of FLEX cable. EVDD pin is connected to power supply of user’s target system via target adapter. If the EVDD pin is floated, the regulator output 5.0Vdc. The ABICS doesn’t power the target system.
The on-board regulator is activated by the RS-232 handshake line DTR. To activate the regulator mannually, set jumper W9.
1.3.2.8 Host System Connector
The host system interface is via a 9-pin DB-9 serial connection plug DEKL­9SAT-F.
