Question:
What about the write/read errors (notes)
Answer:
To continuously write or read data in a 3-wire RTC (S-3511/S-3513/S-35L12/S-3510), be sure to change
“CS” to “L” after the first command has been executed and before the next command is executed. If
commands are continuously executed without changing “CS” to “L,” the second command is
disregarded.
Be sure to change
“CS” to “L.”
