87 / 136 page LTM4676A 87 4676afa For more information www.linear.com/LTM4676A PAGE_PLUS_READ The PAGE_PLUS_READ command provides the ability to set the page within a device, send a command and then read the data returned by the command, all in one communication packet . The value stored in the PAGE command is not affected by PAGE_PLUS_READ. If PAGE_PLUS_READ is used to access data from a non-paged command, the Page Number byte is ignored. This command uses Block Write – Block Read Process Call protocol. An example of the PAGE_PLUS_READ command with PEC is shown in Figure 64. NOTE: PAGE_PLUS commands cannot be nested. A PAGE_PLUS command cannot be used to read or write another PAGE_PLUS command. If this is attempted, the LTM4676A will NACK the entire PAGE_PLUS packet and issue a CML fault for Invalid/Unsupported Data. WRITE_PROTECT The WRITE_PROTECT command is used to control writing to the LTM4676A device. This command does not indicate the status of the WP pin which is defined in the MFR_COMMON command. The WP pin takes precedence over the value of this command unless the WRITE_PROTECT command is more stringent. BYTE MEANING 0x80 Disable all writes except to the WRITE_PROTECT, PAGE, MFR_ EE_UNLOCK and STORE_USER_ALL command 0x40 Disable all writes except to the WRITE_PROTECT, PAGE, MFR_EE_UNLOCK, MFR_CLEAR_PEAKS, STORE_USER_ALL, OPERATION and CLEAR_FAULTS command. individual fault bits can be cleared by writing a 1 to the respective bits in the STATUS registers. 0x20 Disable all writes except to the WRITE_PROTECT, OPERATION, MFR_EE_UNLOCK, MFR_CLEAR_PEAKS, CLEAR_FAULTS, PAGE, ON_OFF_CONFIG, VOUT_COMMAND and STORE_USER_ ALL. Individual fault bits can be cleared by writing a 1 to the respective bits in the STATUS registers. 0x10 Reserved, must be 0 0x08 Reserved, must be 0 0x04 Reserved, must be 0 0x02 Reserved, must be 0 0x01 Reserved, must be 0 Enable writes to all commands when WRITE_PROTECT is set to 0x00. This command has one data byte. appenDix c: pMbus coMManD DeTails Figure 64.
