Abstract

Seriebussprotokoll mellom tilkoplede enheter (50, 52, 54) via en seriebuss (48). Seriebussen (48) inneholder en klokkelinje (SBCK), en start/stopplinje (SBST) og en datalinje (SBDT). Et hovedseriebussgrensesnitt (62, 64, 66) kopler en hovedenhet (50) til seriebussen, og et slaveserie- bussgrensesnitt (63, 65, 67) kopler en eller flere slaveenheter (52, 54) til samme. I en særlig utførelse kan hovedseriebussgrensesnittet (180) omfatte en rrans- aksjonsigangsetter, en datainnlesingsmekanisme, en datautlesingsmekanisme og en klokkedrivenhet. Trans- aksjonsigangsetteren setter i gang en transaksjon ved å trekke start/stopplinjens nivå ned. Datainnlesingsmeka- nismen styrer signalnivået på datalinjen ut fra de data som skal leses inn i slaveenheten. Datalesemekanismen leser data ut ved å overvåke signalnivået på datalinjen. Klokkedrivenheten styrer signalnivået på klokkelinjen i samsvar med et ønsket klokkesignal.Serial bus protocol between connected devices (50, 52, 54) via a serial bus (48). The serial bus (48) contains a clock line (SBCK), a start / stop line (SBST) and a data line (SBDT). A main series bus interface (62, 64, 66) connects a main unit (50) to the serial bus, and a slave series bus interface (63, 65, 67) connects one or more slave units (52, 54) to the same. In a particular embodiment, the main series bus interface (180) may comprise a transaction initiator, a data readout mechanism, a data readout mechanism, and a clock drive. The transaction initiator initiates a transaction by subtracting the start / stop line level. The data entry mechanism controls the signal level of the data line based on the data to be read into the slave unit. The data read mechanism reads data by monitoring the signal level on the data line. The clock driver controls the signal level on the clock line according to a desired clock signal.
