A/D conversion completion flag (RXn0 to RXn3)
CH
A/D conversion completion flag (RXn0 to RXn3) in the corresponding channel
turns on under the following sequential conditions:
• The power is turned on.
• Initial data setting request flag (RY(n+1)9) is turned from off to on.
• As the first A/D conversion is completed in the channel where A/D conversion is
enabled, the digital output value is stored in the remote register.
For an average processing, the flag turns on when the first average processing is
completed and the digital output value is stored in the remote register.
This flag turns on when the AJ65SBT2B-64AD detects a hardware failure. Error reset
request flag (RY(n+1)A) cannot reset (turn off) this flag.
This flag turns on when the user range setting 1 or 2 is configured in the input range
setting and each user range setting value read from a flash memory has an error.
This flag can be reset with Error reset request flag (RY(n+1)A). Turn on Error reset
request flag (RY(n+1)A) and perform the offset/gain setting for all channels that use
the user range setting.
This flag turns on if the write to the flash memory is failed when configuring the offset/
gain setting.
Error reset request flag (RY(n+1)A) cannot reset (turn off) this flag since it indicates
the failure of the AJ65SBT2B-64AD (hardware failure).
This flag turns on when the number of offset/gain setting times exceeds the maximum
of the guaranteed value (10,000 times).
Error reset request flag (RY(n+1)A) can reset (turn off) this flag. However, after this
flag turns on, the setting value acquired by the offset/gain setting is not guaranteed.
This flag turns on when the module moves onto test mode for the offset/gain setting.
This flag turns off when the module moves from test mode to normal mode.
Before performing the offset/gain setting, confirm that this flag is ON.
