(2) Refer to the X9 column for ON/OFF timing.
YA
User range writing
request
[In offset/gain setting mode]
(1) This turns ON when the value for the adjusted offset/gain settings are registered in the A/D
converter module.
(2) Refer to the XA column for ON/OFF timing.
Refer to Section 4.6 for offset/gain settings.
[In normal mode]
(1) This signal turns ON when the user range is restored.
(2) Refer to the field of XA for the ON/OFF timing.
Refer to Chapter 7 for user range restoration.
YB
Channel change
request
(1) This turns ON when changing the channel for which offset/gain settings are to be performed.
(2) Refer to the XB column for ON/OFF timing.
Refer to Section 4.6 for offset/gain settings.
YC
Offset/gain
change request
*1
(1) Turn this signal ON when changing the offset/gain value.
(2) Refer to the field of XC for the ON/OFF timing.
Refer to Section 4.6 for the offset/gain setting.
YD
Maximum value/
minimum value
reset request
(1) Turning ON the Maximum value/minimum value reset request (YD) clears the maximum value/
minimum value stored at any of the buffer memory addresses 30 to 45 (Un\G30 to Un\G45).
(2) Refer to the XD column for ON/OFF timing.
YF
Error clear
request
(1) Turn this signal ON when clearing a write error or input signal error.
(2) Refer to the field of XF or XC for the ON/OFF timing.
