6.The descriptions of the special data registers for the analog functions:

Device	Function
	Average number of times analog input signals are input through CH0~CH3 of
D1062	20EX2/SX2: 1~20, Default = K2
	Average number of times analog input signals are input through CH0~CH2 of
	30EX2: 1~15, Default = K2
D1110	Average value of EX2/SX2 analog input channel 0 (AD 0)
D1111	Average value of EX2/SX2 analog input channel 1 (AD 1)
D1112	Average value of EX2/SX2 analog input channel 2 (AD 2)
	Average value of 20EX2/SX2 analog input channel 3 (AD 3)
D1113	If D1062 is ON, the average value is the current value.
	Displaying the status of the analog input channel of 30EX2
	Please see the explanation below for more information.
	Enable/disable 20EX2/SX2 AD channels
	(0: enable (default) / 1: disable)
D1114	bit0~bit3 sets AD0~AD3.
	30EX2 does not support this function.
D1116	Output value of analog output channel 0 (DA 0) of EX2/SX2
D1117	Output value of analog output channel 1 (DA 1) of 20EX2/SX2
	30EX2 does not support this function.
D1118	For EX2/SX2 series, sampling time of analog/digital conversion. Sampling
	time will be regarded as 2ms If D1118≦2.
