如何在stvd中为stm8 mcu用汇编语言编写选项字节

嗨！
如果你将Forth的这一点翻译成汇编，那么这里是如何做到的。
请注意，' ..'和'（..）'是注释。数据通过数据堆栈传递，您可以在汇编时对其进行编码时将其保存在寄存器中。

将char c存储到（a），将值反转为（a + 1）
：CN！ （c a - ）
 2DUP C！ SWAP NOT SWAP 1+ C！ ;
解锁写保护，存储选项字节
：OPT！ （c a - ）
 FLASH_CR2 DUP C @ $ 80或SWAP CN！解锁选项字节
 ULOCK CN！ LOCK 解锁EEPROM，将c写入（a）;
\来自forth.asm的ULOCK和LOCK：
;锁（ - ）
;锁定EEPROM（STM8S）
 HEADER LOCK'LOCK'
锁：
 BRES FLASH_IAPSR，＃3
 RET
 HEADER ULOCK'ULOCK'
ULOCK：
 MOV FLASH_DUKR，＃0xAE
 MOV FLASH_DUKR，＃0x56
1 $：BTJF FLASH_IAPSR，＃3,1 $; PM0051 4.1在写入之前需要轮询bit3 = 1
 RET

Hi!
If you translate this bit of Forth into assembly, then here is how to do it.
Note that ' ..' and '( .. )' are comments. Data is passed through the data stack, and you can probably keep it in registers when coding it in assembly.
STM8S option setting words
refer to github.com/TG9541/stm8ef/blob/master/LICENSE.md
store char c to (a), inverted value to (a+1)
: CN! ( c a -- )
  2DUP C! SWAP NOT SWAP 1+ C! ;
unlock write protection, store option byte
: OPT! ( c a -- )
  FLASH_CR2 DUP C@ $80 OR SWAP CN!  unlock option bytes
  ULOCK CN! LOCK  unlock EEPROM, write c to (a) ;
\ ULOCK and LOCK from forth.asm:
; LOCK ( -- )
; Lock EEPROM (STM8S)
   HEADER LOCK 'LOCK'
LOCK:
   BRES FLASH_IAPSR,#3
   RET
   HEADER ULOCK 'ULOCK'
ULOCK:
   MOV FLASH_DUKR,#0xAE
   MOV FLASH_DUKR,#0x56
1$: BTJF FLASH_IAPSR,#3,1$ ; PM0051 4.1 requires polling bit3=1 before writing
   RET

这会有用吗？

不，我不认为这会奏效。如果不首先解锁EEPROM，就不能对选项字节进行编程，这是闪存工具在闪存设备时不会做的事情。
您需要在工具链级别（使用类似ST-Link的程序员）或使用IAP（在应用程序编程中）解决此问题。

 第4.1章。这就是上面的代码所做的。可能还有一个STM8库函数来完成它。



以下为原文




No, I don't think that this will work. You can't program the option bytes without unlocking the EEPROM first, and that's something a flash tool won't do while flashing the device.
You need to solve it either it on the tool chain level (using a programmer like ST-Link), or using IAP (in application programming) with the procedure laid out in

Chapter 4.1. That's what the code above does. It's likely that there is also a STM8 library function to do it.
