CR# Attrib.
#115 O R/W Output update time of CH2
#116 O R/W Output update time of CH3
#117 O R/W Output update time of CH4
#118 O R/W LV output mode setting
Symbols:
O: When CR#41 is set to H'5678, the set value of CR will be saved.
X: set value will not be saved.
R: able to read data by using FROM instruction.
W: able to write data by using TO instruction.
※ CR#43: Error status value. See the table below:
bit0 K1 (H'1)
bit1 K2 (H'2)
bit2 K4 (H'4)
bit9 K512(H'0200)
 Note: Each error status is determined by the corresponding bit (b0 ~ b13) and there may be more
than 2 errors occurring at the same time. 0 = normal; 1 = error
※ Module Reset (available for firmware V1.12 or above): When modules need reset, write
H'4352 to CR#0, then wait for one second and then power off and restart. The instruction
initializes all parameter setups. To avoid the resetting process affecting the normal operation
of other modules, it is recommended to connect only one module at a time.
 Explanation on Special Registers D9900~D9999
When DVP-ES2 MPU is connected with modules, registers D9900~D9999 will be
reserved for storing values from modules. You can apply MOV instruction to operate
values in D9900~D9999.
When ES2 MPU is connected with DVP02DA-E2/DVP04DA-E2, the configuration of
special registers is as below:

D9900 D9910
D9901 D9911
D9902 D9912
D9903 D9913
 Adjust D/A Conversion Curve
Users can adjust the conversion curves according to the actual needs by changing the
Offset value (CR#28 ~ CR#31) and Gain value (CR#34 ~ CR#37).
Gain: The corresponding voltage/current input value when the digital output value =
16,000.
Offset: The corresponding voltage/current input value when the digital output value = 0.
 Equation for voltage output Mode0: 0.3125mV = 20V/64,000
