DATA SHEET
µ
PD784044(A), 784046(A)
16-BIT SINGLE-CHIP MICROCONTROLLER
MOS INTEGRATED CIRCUIT
DESCRIPTION
The
µ
PD784046(A) is a model in the
µ
PD784046 subseries within the 78K/IV series. A stricter quality assurance
program applies
µ
PD784046(A) compared to the
µ
PD784046 (standard model). (In terms of NEC’s quality grading,
this is a ”special” grade product.)
The
µ
PD784046(A) is provided with many peripheral hardware functions such as ROM, RAM, I/O port, 10-bit
resolution A/D converter, timer, serial interface, and interrupt functions, in addition to a high-speed, high-performance
CPU.
The
µ
PD784046(A) is under development.
Moreover, a flash memory model,
µ
PD78F4046
Note
, that can operate on the same supply voltage as the mask ROM
model, and many development tools are under development.
Note
Use for functional evaluation only.
The functions are described in detail in the following User’s Manuals. Be sure to read these manuals when
designing your system.

单步进入一个函数后,会改变其它变量的地址,连INfoA中都写入了数据
单步进入一个函数后,会改变其它变量的地址,连INfoA中都写入了数据。 而这个函数并没有用到过那些变量,也没有对InfoA进行操作,就像是跑飞了。 各位有没有遇到过这种情况啊?大概是什么原因 ......
