OUTLINE of PERIPHERAL FUNCTIONS

I/O Ports

The I/O ports consist of nine 8-bit ports: PIOn(n=0 - 8). I/O directions are specified at the bit level. When

configured for input, the pins use high-impedance input.

Flexible Timer

The flexible timer consists of six 16-bit timer channels. Each channel offers independent choice of four

operating modes and of eight count clocks.

-Timer operating modes

- Auto-reload timer

- Compare output

- Pulse width modulation (PWM)

- Capture input

-Timer synchronization

- Timer channels can be started and stopped in union.

-External clocks

- Timer channels 0 and 1 accept external clock signals.

Time Base Generator

The time base generator consists of the time base counter, a frequency divider which derives the time base

signals for the on-chip peripherals from the system clock signals, and watchdog timer, which counts time

base clock cycles and produces a system reset signal when its internal counter overflows.

Asynchronous Serial Interface

The asynchronous serial interface is a serial port that frames each character of information with start and

stop elements. Parameters control transfer speed (using a dedicated baud rate generator), character length,

number of stop bits and use of parity.

-Built-in baud rate generator

-Character length: 7 or 8 bits

-Stop bits: 1 or 2

-Parity: none, odd, or even

-Error detection for receiving: parity, framing and overrun errors

-Full duplex operation

Clock Synchronous Serial Interface

The clock synchronous serial interface are two channels of serial ports that transmit 8-bit data

synchronized with internal or external clock signals.
