Service-based Concept

EEPROM. The master system control is performed by firmware. General chip-wide settings are loaded from the EEPROM to

hardware registers during system initialization. During start-up of a transmit or receive mode the specific settings are loaded

from the EEPROM or SRAM to the current service in the SRAM and from there to the corresponding hardware registers.

A complete configuration set of the transceiver is called “service” and includes RF settings, demodulation settings, and

telegram handling information. Each service contains three channels which differ in the RF receive or transmit frequencies.

The Atmel ATA8510/15 supports five services which can be configured in various ways to meet customer requirements.

Three service configurations are located in the EEPROM space. They are fixed configurations which should not be changed

during runtime.

Two service configurations are located in the SRAM space and can be modified by USER SW in a Flash application or by an

SPI command during IDLEMode.

A service consists of

●

One service-specific configuration part

●

Three channel-specific configuration parts

Further configurations for PollingMode and RSSI are available and can be modified in IDLEMode via an SPI command

and/or User SW.

Figure 2-1 gives an overview on the service based-concept.
