使用默认IAR工程，短接PA10和PB3引脚。

预期输出是

read pin value: 0x00000000
read pin value: 0x00000400
read pin value: 0x00000000
read pin value: 0x00000400
......

实际输出是：

read pin value: 0x00000000
read pin value: 0x00000000
read pin value: 0x00000400
read pin value: 0x00000000
read pin value: 0x00000400
......

AIC8800M的PB口是异步的，PA口是同步的，交互操作，可能会有时序问题。
