Caution points:
1. The PON bit is a power-on reset flag bit.
The PON bit is set to "1" when a reset occurs, such as during the initial power-up or when recovering from a
supply voltage drop. At the same time, all bits in the Control 1 and Control 2 registers except for the PON and /
XST bits are reset to "0".
Note: At this point, all other register values are undefined, so be sure to perform a reset before using the module.
Also, be sure to avoid entering incorrect date and time data, as clock operations are not guaranteed when
the time data is incorrect.
2. The TEST bit is used by the manufacturer for testing. Be sure to set "0" for this bit.
3. Address D (a reserved register) is used for the manufacturer's settings. Do not read from or write to this register.
4. All bits marked with a " 0 " in the above table should be set as "0". Their value when read will be "0".
5. All bits marked with " ! " are read-only bits. Their value when read is always "0".
6. When PON bit became 1 because power-on reset function worked, /CLEN1 and /CLEN2 bit become 0.
When /CLEN1 and /CLEN2 bit become 1, FOUT output stops.
