MCS -96• The mcs-96 is a family of microcontrollers (MCU) commonly used in

embedded systems. The family is often referred to as 8xC196 family. These MCU’s are commonly used in hdd, modems, printers.

• The MSC-96 family members are all high performance microcontroller with a 16 bit CPU and atleast 230 bytes of on-chip RAM.

• CPU :The major components of the MCS-96 CPU are the Register File and the Register / Arithmetic Logic Unit (RALU). The RALU contains a 17bit ALU, the program status word (PSW), the program Counter (PC), a loop counter and three temporary registers.

• Interrupts – There are 21 interrupts sources and 8 interrupt vector on the 8096. When the interrupt controller detects one of the 8 interrupts it sets the corresponding bit in the interrupt pending register. Individual interrupts are enabled or disabled by setting or clearing bits in the interrupt mask register.

• Timers – The 8096 has two 16 bit timers. Timer 1 and Timer 2.• Standard I/O Ports • The 8096 has five 8 bit I/O ports.• Port 0 is an input port that is also the analog input for the A/D

converter.• Port 1 is a quasi-bidirectional port.• Port 2 contains three types of port lines.• Quasi-Bidirectional, input and output. Other functions on the 8096

share the input and output lines with Port 2.• Port 3 and 4 are open-drain bidirectional ports that share their pins

with the address/data bus.• High Speed Input Unit (HSI)

The 8096 HIS unit can record times of external events with a 9 state time resolution. It can monitor four independently configurable HSI lines and captures the value of timer 1 when events takes place.

• High Speed Output Unit (HSO)– The 8096 HSO unit can trigger events at specified times based on Timer1 or Timer2.

• These programmable events include: starting an A/D conversion, resetting Timer2, generating upto four software time delays, and setting or clearing one or more of the six HSO output lines.

• Serial Port– The serial port on the 8096 has one synchronous (Mode 0) and three asynchronous modes (Modes 1, 2 and 3).

• The asynchronous modes are full duplex..• Pulse Width Modulator (PWM) – The PWM output waveform is a variable duty

cycle pulse that repeats every 256 state times. The PWM output can perform digital to analog

• conversions and drive several types of motors that require a PWM waveform for more efficient operation.

• A/D Converter– The 8096 A/D converts an analog input to a 10 bit digital equivalent.

• The main components of the A/D Converter are: 8 analog inputs, an 8 to 1 multiplexer, a sample and hold capacitor and resistor ladder.
