With DATA_TYPE > 000b, the TMAG5170D-Q1 supports a special 32-bit SDO frame for two-channel simultaneous data read. Each channel data is limited to 12 bits. This feature is useful for systems requiring faster data throughput while performing multi-axis measurements. Figure 6-8 explains the detail construction of the special 32-bit SDO frame. When the device is set to special 32-bit read, the device will continue to deliver the 2-channel data set through the SDO line during consecutive read or write cycles. DATA_TYPE bits must be reset to get back to a regular read cycle. Only four status bits are transmitted in this mode. All the status bits except for the ERROR_STAT bit are directly read from the status registers. The ERROR_STAT bit indicates if any error bit set in the device. The status bits, STAT[2:0], can be changed based off CMD1 value in the previous frame.
