The SY10/100E142 are high-speed 9-bit shift registers
designed for use in new, high-performance ECL systems.
The E142 can accept serial or parallel data to be shifted out
in one direction as both serial and parallel outputs. The
nine inputs, D
0
-D
8
, accept parallel input data, while S-IN
accepts serial input data.
The SEL (Select) control pin serves to determine the
mode of operation, either SHIFT or LOAD. The shift direction
is from bit 0 to bit 8. The input data has to meet the set-up
time before being clocked into the nine input registers on
the rising edge of CLK
1
or CLK
2
. Shifting is also performed
on the rising edge of either CLK
1
or CLK
2
. The MR (Master
Reset) control signal asynchronously resets all nine
registers to a logic LOW when a logic HIGH is applied to
MR.
The E142 is designed for applications such as diagnostic
scan registers, parallel-to-serial conversions and is also
suitable for byte-wide parity.

C++ 属于面向对象的编程语言,OOP的思想不必多说,特别对于复杂的软件工程来说,利用OOP绝对是事半功倍,相对于传统的C来说; 当然用C来写单片机程序无可厚非,已经延续了一个传统,从大学时学的开始到工作岗位,好多人都是一直用C来做,但是既然Keil支持C++编译, 可以用C++来编写你的代码,可以利用高级语言来结构化,清晰化你的程序,为嘛不用呢!哈哈,个人看法!下面进入正题: C+...[详细]
