+## 4. Output Modes
110
+
111
+### Continuous Output
112
+1. Set output mode register (0x03) to 0.
113
+2. Send read data frame (set start register and count).
114
+
115
+### Query Output
116
+1. Set output mode register (0x03) to 1.
117
+2. Send read data frame each time you want data.
118
+
119
+*Note: Output format is set by the read data frame. Mode is set by register 0x03.*

127
+
128
+- Use [GY_UVI.zip] for Windows.
129
+- Select the COM port connected to the module, baud rate, and ID (default 0xA4, or 0x00 if unknown).
130
+- **Config reg:** This section corresponds to configurable registers. After changing any register, press Enter or click elsewhere to write the config to the module.
131
+- **Read reg:** This section is for reading module registers. Set the start register and number of registers to read, then click "read" to send the command.
132
+
133
+### Continuous Mode
134
+1. Set start register and number of registers to read.
135
+2. Set update rate.
136
+3. Set mode to continuous.
137
+
138
+### Query Mode
139
+1. Set start register and number of registers to read.
140
+2. Set update rate.
141
+3. Set mode to query.
142
+4. For each query, repeat step 1 (send read register frame).

19
+The MAX9812 is a single amplifier in a 6-pin SC70 package (2mm x 2.1mm) and the MAX9813 is a dual- input amplifier available in an 8-pin SOT23 (3mm x 3mm) package.
20

21
+**The MAX9813 has two inputs allowing two microphones to be multiplexed to a single output.**
22
+
23
+The MAX9812/MAX9813 are offered in two grades. The MAX9812L/MAX9813L are optimized for 3.3V supply operation (2.7V to 3.6V).
24
+
25
+The MAX9812H/MAX9813H are PC2001 compliant and are optimized for 5V operation (4.5V to 5.5V). Both devices are specified over the -40°C to +85°C extended operating temperature range.

-The MAX9812 is a single amplifier in a 6-pin SC70 package (2mm x 2.1mm) and the MAX9813 is a dual- input amplifier available in an 8-pin SOT23 (3mm x 3mm) package. The MAX9813 has two inputs allowing two microphones to be multiplexed to a single output.
18
-
19
-The MAX9812/MAX9813 are offered in two grades. The MAX9812L/MAX9813L are optimized for 3.3V supply operation (2.7V to 3.6V).
20
-
21
-The MAX9812H/MAX9813H are PC2001 compliant and are optimized for 5V operation (4.5V to 5.5V). Both devices are specified over the -40°C to +85°C extended operating temperature range.

- **Powering**: ECMs need a bias voltage to function, whereas the MAX9812 and ICS-41434 use internal power supplies (usually lower voltage).
19 19
- **Signal Output**: ECMs give an analog output that often requires additional processing, while the MAX9812 provides analog output with built-in gain control, and the ICS-41434 outputs a digital signal (I2S) directly.
