5) /CLEN1 bit
This bit is controlling FOUT output with /CLEN2 bit.
When /CLEN1 and /CLEN2 bit set to 1 even if FOE input is "H", FOUT output stops.
If FOUT output is unnecessary, it functions as RAM-bit and is ( FOE="L" )
When PON bit became 1 because power-on reset function worked, /CLEN1 and /CLEN2 bit become 0.
6) CTFG bit
During a read operation, this bit indicates the /INTA pin's priodic interrupt output status.
This status can be set as OFF by writing a "0" to this bit when /INTA = " L".
CTFG
Data
Description
0
A "0" can be written only when the periodic interrupt is in level
mode, at which time the /INTA pin is set to OFF (Hi-z) status.
(Only when Alarm_D does not match)
After a "0" is written, the value still becomes "1" again at the
next cycle.
Default
Write
1
Setting prohibited (do not set this bit value, even though it has no
effect)
0
Periodic interrupt output OFF status; /INTA = OFF (Hi-z)
Default
Read
1
Periodic interrupt output ON status; /INTA = "L"
For details, see "8.4. Periodic Interrupt Function".
7) WAFG bit
This bit is valid only when the WALE bit value is "1". The WAFG bit value becomes "1" when Alarm W has
occurred.
The /INTB = "L" status that is set at this time can be set to OFF by writing a "0" to this bit.
WAFG
Data
Description
0
/INTB pin = OFF (Hi-z)
Default
Write
1
Setting prohibited (do not set this bit value, even though it has no
effect)
0
Alarm_W time setting does not match current time
(This bit's value is always "0" when the WALE bit's setting is "0")
Default
Read
1
Alarm_W setting matches current time
(Result is that bit value is held until cleared to zero)
For details, see "8.5. Alarm W Function".
8) DAFG bit
This bit is valid only when the DALE bit value is "1". The DAFG bit value becomes "1" when Alarm D has
occurred.
The /INTA = "L" status that is set at this time can be set to OFF by writing a "0" to this bit.
DAFG
Data
Description
0
/INTA pin = OFF (Hi-z) (but only when the periodic interrupt
output status is OFF)
Default
Write
1
Setting prohibited (do not set this bit value, even though it has no
effect)
0
Alarm_D time setting does not match current time
(This bit's value is always "0" when the DALE bit's setting is "0")
Default
Read
1
Alarm_D time setting matches current time
(result is that bit value is held until cleared to zero)
For details, see "8.6. Alarm D function".
