9.5.2.6 SDATAC: Stop Read Data Continuous Mode Command

The SDATAC command stops read-data-continuous mode. This mode is required before sending register read or write commands and before issuing the data read command (RDATA). CS high cancels the SDATAC mode. Send the RDATAC command to cancel SDATAC mode; see the Stop-Read-Data-Continuous-Mode (SDATAC) section for more details.
