The gain can be set by setting the GAIN0 to GAIN5 pins to high or low.
In the combined I
are valid when all the GAIN0 to GAIN5 pins are low. Since the initial setting of the I
the setting that is established when GAIN0 to GAIN5 are low in the initial state after reset release.
Table 2.9 shows the gain settings established according to the GAIN0 to GAIN5 pins. The gain settings established
according to the pin 6 bits and the gain settings established according to the register 6 bits are identical, so refer to Table
8.2.1 for the detailed settings.
MUTEB is the low active soft mute pin that controls both the left and right channels.
In the combined I
valid when MUTEB is low. Since the initial setting of the I
established when MUTEB is low in the initial state after reset release.
Table 2.10 shows the MUTEB function settings.
TEST and MODE are the test pins. TEST and MODE must be low while using the LV4904V.
