Pulse width modulation

Pulse width measuring

8-bit Pulse accumulator

Two major modes of operation

Simple event counter

Gated time accumulation

Clocked by internal source or external pin

Full-duplex UART - SCI

Standard Nonreturn to Zero format (NRZ)

8 or 9 bit data transfer

Integrated baud rate generator

Enhanced receiver data sampling technique

Noise, Overrun and Framing error detection

IDLE and BREAK characters generation

Wake-up block to recognize UART wake-up

from IDLE condition

Three SCI related interrupts

SPI – Master and Slave Serial Peripheral

Interface

Supports speeds up ¼ of system clock

Software selectable polarity and phase of se-

rial clock SCK

System errors detection

Allows operation from a wide range of system

clock frequencies (build-in 5-bit timer)
