EEPROM_UpdateBankStatus

EEPROM_UpdateBankStatus() 函数的功能是更新 EEPROM 组状态。此函数由 EEPROM_Write() 函数调用。首先读取 EEPROM 组状态,以确定如何继续。

Bank_Status[0] = *(Bank_Pointer);
Page_Status[0] = *(Page_Pointer); 

如果此状态表示 EEPROM 组为空,则状态会更改为当前并进行编程。

// Set Bank Status to Current Bank
Bank_Status[0] = CURRENT_BANK;
Bank_Status[1] = CURRENT_BANK;
Bank_Status[2] = CURRENT_BANK;
Bank_Status[3] = CURRENT_BANK;

// Clears status of previous Flash operation
ClearFSMStatus();

Fapi_setupBankSectorEnable(FLASH_WRAPPER_PROGRAM_BASE+FLASH_O_CMDWEPROTA, WE_Protection_A_Mask);
Fapi_setupBankSectorEnable(FLASH_WRAPPER_PROGRAM_BASE+FLASH_O_CMDWEPROTB. WE_Protection_B_Mask);

// Program Bank Status to current bank
oReturnCheck = Fapi_issueProgrammingCommand((uint32*) Bank_Pointer,
                                               Bank_Status, 4, 0, 0,
                                                 Fapi_AutoEccGeneration);

// Wait for completion and check for any programming errors
EEPROM_CheckStatus(&oReturnCheck);

// Set Page Pointer to first page of current bank
Page_Counter = 0;
Page_Pointer = Bank_Pointer + 8;

如果状态不为空,则接下来检查是否存在其中的所有页面都被使用的当前 EEPROM 组(已满 EEPROM 组)。在这种情况下,当前 EEPROM 组状态将更新以显示 EEPROM 组已满,并且下一个 EEPROM 组状态将更新为当前以允许对下一个 EEPROM 组进行编程。最后,页面指针会更新为新 EEPROM 组的第一页。

// Set Bank Status to Used Bank
Bank_Status[0] = CURRENT_BANK;
Bank_Status[1] = CURRENT_BANK;
Bank_Status[2] = CURRENT_BANK;
Bank_Status[3] = CURRENT_BANK;

// Clears status of previous Flash operation
ClearFSMStatus();

Fapi_setupBankSectorEnable(FLASH_WRAPPER_PROGRAM_BASE+FLASH_O_CMDWEPROTA, WE_Protection_A_Mask);
Fapi_setupBankSectorEnable(FLASH_WRAPPER_PROGRAM_BASE+FLASH_O_CMDWEPROTB, WE_Protection_B_Mask);

// Program Bank Status to full bank
oReturnCheck = Fapi_issueProgrammingCommand((uint32*) Bank_Pointer + 2,
                                              Bank_Status, 4, 0, 0,
                                                 Fapi_AutoEccGeneration);

// Wait for completion and check for any programming errors
EEPROM_CheckStatus(&oReturnCheck);

// Increment Bank Pointer to next bank
Bank_Pointer += Bank_Size;

// Set Bank Status to Current Bank
Bank_Status[0] = CURRENT_BANK;
Bank_Status[1] = CURRENT_BANK;
Bank_Status[2] = CURRENT_BANK;
Bank_Status[3] = CURRENT_BANK;

// Clears status of previous Flash operation
ClearFSMStatus();
Fapi_setupBankSectorEnable(FLASH_WRAPPER_PROGRAM_BASE+FLASH_O_CMDWEPROTA, WE_Protection_A_Mask);
Fapi_setupBankSectorEnable(FLASH_WRAPPER_PROGRAM_BASE+FLASH_O_CMDWEPROTB, WE_Protection_B_Mask);

// Program Bank Status to current bank
oReturnCheck = Fapi_issueProgrammingCommand((uint32*) Bank_Pointer,
                                              Bank_Status, 4, 0, 0,
                                                 Fapi_AutoEccGeneration);

// Wait for completion and check for any programming errors
EEPROM_CheckStatus(&oReturnCheck);

// Set Page Pointer to first page of current bank
Page_Counter = 0;
Page_Pointer = Bank_Pointer + 8;
