6. Function Specification

6.1 OPERATING PRINCIPLES & METHODS

6.10 I/O Buffer

Input buffer controls the status between the enable the and disable of chip. Unless the CS1 to CS2 is in active mode. Input or output of data and instruction does not execute. Therefore internal stade is not change.

Bust RSTB and ADC can operate regardless CS1-CS2. 6.11 Input register

Input register is provided to interface with MPU which is different operating frequency. I …… 此处隐藏：12341字，全部文档内容请下载后查看。喜欢就下载吧 ……
