The A/D conversion completion flag turns on at completion of the A/D conversion of

 

 

 

the corresponding channel when the initial data setting request flag (RY(n+1)9) turns

 

 

 

from off to on after power-on.

 

 

 

The A/D conversion completion flag processing is processed only once when the A/D

Turns on if all channels are not set to any of "user range settings 1 to 3" at offset/gain

setting (in the test mode).

 

E2PROM write error flag

Turns on if the number of E2PROM write times exceeds its limit (100,000 times per

RXnC

channel). If this flag has turned on, this module itself has failed (hardware fault) and

 

 

 

therefore this flag cannot be reset (turned off) by the error reset request flag.

RXnF

Test mode flag

Turns on in the test mode.

(Used for interlock to prevent wrong output during offset/gain setting.)

 

 

 

 

 

 

After power-on, the initial data processing request flag is turned on by the AJ65SBT-

 

 

 

64AD to request the initial data to be set.

 

 

 

Also, after the initial data processing is complete (initial data processing completion
