今天用了一下IAR-STM8，简单的代码可以正确执行，再把项目文件移植过程后无**确运行；后来想起了STVD4.11中STM8S系列的头文件有问题，仔细核对，真的一摸一样，于是手工修改TIM4的定义，运行基本正常；
STVD4.14 .h
/* 8-Bit Timer 4 (TIM4) */
/*****************************************************************/

DEF_8BIT_REG_AT(TIM4_CR1,0x5340);
/* TIM4 Interrupt enable register */
DEF_8BIT_REG_AT(TIM4_IER,0x5343);
/* TIM4 Status register */
DEF_8BIT_REG_AT(TIM4_SR,0x5344);
/* TIM4 Event Generation register */
DEF_8BIT_REG_AT(TIM4_EGR,0x5345);

DEF_8BIT_REG_AT(TIM4_CNTR,0x5346);
/* TIM4 Prescaler register */
DEF_8BIT_REG_AT(TIM4_PSCR,0x5347);
/* TIM4 Auto-reload register */

可以看一下，最后一个定义不同地址 |
