(2) Internal RAM data status register (RAMS)
The RAMS register is a special register. This can be written only in a special combination of sequences (see 3.4.8
Special registers).
This register is a flag register that indicates whether the internal RAM is valid or not.
This register can be read or written in 8-bit or 1-bit units.
The set/clear conditions for the RAMF bit are shown below.
• Setting conditions: Detection of voltage lower than specified level
• Clearing condition: Writing of 0 in specific sequence
RAMS
After reset: 01H
Note This register is reset only when a voltage drop below the RAM retention voltage is detected.
