DESCRIPTION

The Simtek STK11C48 is a fast static

RAM

with a

nonvolatile element incorporated in each static

memory cell. The

SRAM

can be read and written an

unlimited number of times, while independent, non-

volatile data resides in the Nonvolatile Elements.

Data transfers from the

SRAM

to the Nonvolatile Ele-

ments (the

STORE

operation), or from Nonvolatile

Elements to

SRAM

(the

RECALL

operation), take

place using a software sequence. Transfers from the

Nonvolatile Elements to the

SRAM

(the

RECALL

operation) also take place automatically on restora-

tion of power.

What is the reason for this situation in the microcontroller?: I recently used a chip, and then I called the math.h file to calculate. For example, I used sin, and sin(144/360) was OK. But if I separated it, c=144/360, sin(c), it would report an error. Similarly,...; 乱起东城 MCU
