摘要： A serial peripheral interface (SPI) communication system includes a memory configured with a start register address and an end register address that define a register address range for a data operation; a chip select terminal configured to receive a chip select signal comprising an active and idle signal levels that define a plurality of chip select frames; a serial data input terminal configured to receive a master out, slave in (MOSI) signal, wherein the MOSI signal includes configuration information received in a first chip select frame of the data operation, wherein the configuration information includes an operation command bit indicating whether the data operation is a write operation or a read out operation and an auto-incrementation control bit indicating whether automatic register address incrementation across chip select frames is enabled or disabled; and a serial data output terminal configured to transmit a master in, slave out (MISO) signal.

摘要： A magnetic field sensor arrangement includes a magnetic field sensor element configured to provide a sensor output signal responsive to a magnetic field, wherein the sensor output signal is representative of a magnetic field amplitude; a processing module configured to provide a processed sensor output signal representative of the sensor output signal; a switching level calculation module configured to calculate a switching level, (1) during a power up mode, based on a default switching level, and (2) during a running mode, based on the processed sensor output signal; a comparator module configured to compare the processed sensor output signal with the switching level, and to provide a comparator output signal based on the comparison; and a storage module configured to store the default switching level, provide the default switching level during the power up mode, and update the default switching level during the running mode.

摘要： A magnetic field sensor apparatus includes a sensor signal generator generating a sensor signal responsive to a magnetic field. A switching level provider provides during a power up mode a switching level based on a most recently updated valid one of a first and a second value of a default switching level. If an update triggering condition occurs, the not most recently updated one of the first and second values of the default switching level is updated and the most recently updated one of the first and second values of the default switching level is maintained unchanged until a next update triggering condition occurs, so that the first and second values of the default switching level are updated alternately on consecutive triggering conditions.
