REFRESH_CONFIGURATION This command is used to set refresh configuration and get the refresh status. Table 105. Register 0xF4—REFRESH_CONFIGURATION (for BLOCK R) Byte Byte Name R/W Description 0 Parameter length Block W Parameter data length—fixed to 1. 1 Parameter Block W 0x00: get auto-refresh interval. 0x01: get auto-refresh enabled/disabled status. Others: get all status, including refresh enable/disable, autorefresh enable/disable, refresh times, recalculate CRC error times, autorefresh interval. 0 Data length Block R Number of bytes of data for this block read (1 to 8). [8:1] Data Block R Parameters: 0x00: get autorefresh interval, Bytes[2:1] are the autorefresh interval. 0x01: get autorefresh enabled/disabled status. If Byte 1 is 0, autorefresh is disabled. Others: get all status, including refresh enable/disable, autorefresh enable/disable, refresh times, recalculate CRC error times, autorefresh interval, Bytes[8:1]: Byte Byte Name Description 1 Refresh status 0: refresh is done. 1: refresh is running. 2 Autorefreshing 0: autorefresh is disabled. 1: autorefresh is enabled. [4:3] Refresh count Refresh times. [6:5] Recalculate error count Recalculate error times. [8:7] Autorefresh interval Autorefresh interval, unit: day. |
