说明： 这是一个非常小而简单的模块，它通过一个键xy矩阵扫描，并产生一种“快照”的
位的代表在扫描采样的按键开关状态。
有在模块的内存，使输出保持不变的扫描过程中，并同步更新。
把钥匙是连续取样，但向上的按键开关存储器存储的所有数据，直到最后输出
“快照”的生产。
该模块是Verilog的参数，并与小矩阵式键盘推荐使用。据
在实际测试硬件。
(This is a very small and simple module, which scans through an X-Y matrix of keys, and produces a "snapshot" of
bits which represent the sampled state of the keyswitches during the scan.
There is memory in the module, so that the outputs are held constant during a scan, and updated simultaneously.
The keys are sampled sequentially, but the memory stores up all of the keyswitch data until the final output
"snapshot" is produced.
This module is parameterized Verilog, and is recommended for use with small matrix type keypads. It has been
tested in real hardware. )
