IC description

1.1.9 PWM Output

Control of TV settings is able to be made with up to eight

8-bit PWM outputs, with a frequency maximum of

23,437Hz at 8-bit resolution(INTCLK=12 MHz). Low reso-

lutions with higher frequency operation can be pro-

grammed.

1.1.10 Serial Peripheral Interface (SPI)

The SPI bus is used to communicate with external

devices via the SPI, or bus communication stan-

dards. The SPI uses one or two lines for serial data and a

synchronous clock signal.

1.1.11 Standard Timer (STIM)

The Standard Timer includes a programmable 16-bit

down counter and an associated 8-bit prescaler with Sin-

gle and Continuous counting modes.

1.1.12 Analog/Digital Converter (ADC)

In addition there is a 3 channel Analog to Digital Con-

verter with integral sample and hold, fast 5.7us conver-

sion timer and 6-bit guaranteed resolution.
