Thus, tuning can be accomplished via a 2-byte serial transfer to the 16-bit N register.

因此通过16比特N寄存器的2字节串行转换，调谐就可以实现。

The most obvious issue is that the interface in Listing 6 requires a JNI call for each bit set or retrieved, as well as a JNI call to read a byte from, or write a byte to, the serial port.

最显著的一个问题就是，清单6中的接口在设置或检索每个位，以及从串行端口读取字节或者向串行端口写入字节都需要一个JNI调用。
