Question:
What about the basic terms (memory protect, reset, CS)
Answer:
Memory protect, reset
→
S-29xx1A, S-29x94A, S-29x55A
Function for prohibiting a write command from being executed in a certain region of the memory space.
This function is enabled by controlling the protect or reset input pin (select/deselect protect). This reset
prevents the microcomputer from running uncontrollably and also prevents false-writes caused by noise
in order to protect data.
Ex.: Storage of ID codes and product shipment adjustment data
(Note) S-29xx1A and S-29x94A protect 50% of memory, starting with the leading address.
CS, /CS (/CS: S-29x55A, S-29x94A)
CS is an input pin used to select the execution of a command. It is selected using “H” and deselected
using “L” (the reverse is true for /CS)
→
/CS is useful on the interface of the microcomputer (L active is mainly used for the microcomputer).
Malfunction, however, is likely to be caused by noise upon power-on if a command is executed at the
GND level.
