STM8S001是一顆I/O相當複雜的MCU，如下表：
| Pin | Port |
|---|---|
| 1 | PD6/AIN6/UART1_RX、PA1/OSCIN |
| 5 | PA3/TIM2_CH3[SPI_NSS]\[UART1_TX]、PB5/I2C_SDA[TIM1_BKIN] |
| 6 | PB4/I2C_SCL/[ADC_ETR] |
| 7 | PC3/TIM1_CH3[TLI][TIM1_CH1N]、PC4/CLK_CCO/TIM1_CH4/[AIN2]/[TIM1_CH2N]、PC5/SPI_SCK[TIM2_CH1] |
| 8 | PC6/SPI_MOSI[TIM1_CH1]、PD1/SWIM、PD3/AIN4/TIM2_CH2/ADC_ETR、PD5/AIN5/UART1_TX |
例如：PD6和PA1同時綁到第一隻腳，因此，操作一般GPIO時，PD6和PA1是一樣的結果，但是切換到其它功能時，則不同運作，如設定AIN6或者OSCIN

P.S. 如果燒錄失敗，實屬正常，再次執行燒錄命令即可，如果無法unlock(-u)，請更換其它IC
完成
