我为PIC18F87做了一个程序，还行。然后我必须把相同的代码迁移到PIC18F4620。该代码具有LCD、UART和七段显示器的接口。最后，所有的问题都在运行…除了EEPROM写函数。这个函数有不稳定的行为。我用的代码和数据表是一样的：EEPROFBCFECONE1，EEPGD；EngDeloBcCfEnEn1，CFGS；1＝CONFIG。寄存器，0＝闪存O DAT0S.BSFEFEC1，WRE；HabiTeA ECRITURBABCIMCONTRON，GIE；DeHabistIa中断；MOVLW0x5MOVL2WAXAMOVOVWEF2BSFEFECO1，WR；BSFIMTCON，GIE；Habista中断；用户代码执行；用户代码执行BCFEFECO1，WRN；DeHabista ESCRITURA AL完成（EEIF集）BCFPIR2，EEFEURTURNI AM写入10个连续的循环：CyeDefBANCO，0；BANCO 1MOVWMNCNDMOVLW0XAM0VFWMulPLRCALMYPYS；（BANCO-1）*10MOVFLYBY字节，WMOVWWDATAWAYAXADYDR；Valor表DFSMOVFWFFRSR0LANDERMOVEVFDF0，WMOVWFDATAYEEDATAL写的CurfDATAEE该程序具有用于EUSAT功能的高中断例程。每次接收到来自EUART的消息时，都有中断，称为InIT例程。这个特性运行正常！高科代码0x000 08GotoIndiTI真的混淆了这个PIC中的中断功能。我不知道EEPROM写的问题是由于中断…还是我的代码…或者…我会感谢你们在这个问题上的善意支持。 以上来自于百度翻译 以下为原文 I made a program for PIC18f887 and was OK.Then I have to migrate the same code to the PIC 18F4620. The code have interfaces to LCD, UART and 7 segments displays. Finally, all issues are running OK....except the EEPROM write function.This function has and erratic behavior.The code I am using to write is the same one of the data sheet: ; RUTINA ESCRIBIR EN EEPROMWRITEMOVF DATA_EE_ADDRH,WMOVWF EEADRHMOVF DATA_EE_ADDR,WMOVWF EEADRMOVF DATA_EE_DATA,WMOVWF EEDATA; DATO A SER ESCRITO EN LA EEPROMBCFEECON1,EEPGD; SERA EN LA MEMORIA DE DATOSBCFEECON1,CFGS ; 1=CONFIG.

Each time its a received message from EUART, there is the interruption and its called the INNIT routine. This feature is running OK! HIGH_INTCODE 0x0008GOTO INNITI am really confused about how the interruptions function in this PIC. I do not know if the problem with the EEPROM write is due to interruptions...or my code...or.....I will appreciate your kind support in this issue.
