[参考译文] RM57L843：写入&quot；ESM 低电平时间计数器预加载寄存器&quot；(ESMLTCPR)不起作用

您好！  

使用以下例程写入"ESM 低电平时间计数器预加载"(ESMLTCPR)寄存器不会更改它、也不会更改"ESM 低电平时间计数器"(ESMLTCR)寄存器、即使在 ERROR 引脚状态强制为低电平时也是如此。

/** @fn void esmSetCounterPreloadValue(uint32 value)
*   @brief Set counter preload value
*
*   @param[in] value - Counter preload value
*
*   Set counter preload value.
*/
/* SourceId : ESM_SourceId_018 */
/* DesignId : ESM_DesignId_018 */
/* Requirements : HL_CONQ_ESM_SR11 */
void esmSetCounterPreloadValue(uint32 value)
{
/* USER CODE BEGIN (37) */
/* USER CODE END */

    esmREG->LTCPR = value & 0xC000U;

/* USER CODE BEGIN (38) */
/* USER CODE END */
}

此致、
