Registers Format  27
3.9 Clear Interrupt Register
To read this port can generate clear interrupt signal. No matter which
interrupt source is used, the clear interrupt register must be read to allow
next interrupt.
Address : BASE + 9
Attribute : read only

3.10 Software A/D Trigger Register
To read this port can generate A/D trigger signal if the AD mode control
register is set to use internal software A/D trigger source.
Address : BASE + 10
Attribute : read only

3.11 DA Data Registers
There are two DA channels in ACL-8316. The address Base + 4 is DA
channel 1 and the address Base +6 is DA channel 2. DA11 is Most
Significant Bit, and DA0 is Least Significant Bit. The lowest 4 bits of this
register is don‘t cared. Users can consider the DA data values as 16-bits
with the lowest 4 bits are truncated. Therefore, result in 12-bits resolution
although the DA data value is in the range from 0 to 65535.
Address : BASE + 4 and BASE+6
Attribute : write only
