CLEAR - CLEAR control register (address 34h) bit allocation Bit 7 6 5 4 3 2 1 0 Symbol POR ILLEGAL _ COMMAND MTP_LOCK REG_ILLE GAL_ACCESS MTP_ILLE GAL_ACCESS MTP_ACC ESS_STATUS CLR_ OC CLR_ SC Reset 0 0 0 0 0 0 0 0 Access R/W R/W R/W R/W R/W R/W R/W R/W Table 12. CLEAR - CLEAR control register (address 34h) bit description Bit Symbol Description 7 POR Power-on-reset (POR) 0 — A power-on-reset has happened due to any external interference or power supply fail 1 — Set by the microcontroller during the MLC startup The microcontroller can check this bit status to know if a POR has happened. If so, the MLC must be programmed with the values of the desired registers again, because after a POR, the MLC returns to the default values. 6 ILLEGAL _COMMAND Illegal command 0 — The MLC received a valid command. 1 — The microcontroller sent a nonexisting command, a wrong message configuration or a command that is restricted to a different part number. The microcontroller writes a 1 in this location to clear the flag. 5 MTP_LOCK MTP lock 0 — The MTP is available to be read/write. 1 — The user attempt to read / write in the MTP with a wrong key for 3 consecutive times. The MTP is not accessible by the micro. 4 REG_ILLEGAL_ACCESS Register illegal access 0 — The selected register is accessible by the microcontroller. 1 — The microcontroller tries to write/read in an invalid register. If the value of this bit is 0 after writing or reading a register, then the action was performed in a valid register. The microcontroller writes a 1 in this location to clear the flag. The flag is not stopping the communication. 3 MTP_ILLEGAL_ACCESS MTP illegal access 0 — The register the microcontroller is trying to access is not restricted 1 — The microcontroller is trying to read/write in a restricted register. The microcontroller should write a 1 in this location to clear the flag. 2 MTP_ACCESS_STATUS MTP access status 0 — The MLC was not able to access the required MTP register 1 — The MLC succeeded accessing the required MTP register. The microcontroller should write a 1 in this location to clear the flag Note: If neither MTP_ACCESS_STATUS, MTP_ILLEGAL_STATUS or ILLEGAL_COMMAND is set after MTP read/write request, the request is ignored due to an internal MTP function. The microcontroller must repeat the action. 1 CLR_OC Clear open-circuit detection 0 — Always 0 when the microcontroller reads it. 1 — Write a 1 in this location to clear all the OC flags and restart the channels. |
