Using Events, Logic, And IR
9 - 11
Depending on the logic output mode, there are additional events that are gen-
erated as summarized in the table below.
Toggle All Mics Mute
Table Mic Mute Event This event maps the mute state of the microphone to
clink_mute. If the microphone is muted (mute=1), then
the value of clink_mute will be set to 1 on SoundStruc-
ture device 1. If the microphone is unmuted (mute=0)
then the value of clink_mute will be set to 0 on Sound-
Structure device 1. There is another event, Clink to Mics
Mute which maps the clink_mute state on this device to
mute the virtual channel (or group) “Mics”. The net
result is that the mute state of all microphones in the
group “Mics” are toggled when the switch is closed.
Table Mic Button Event When the microphone switch is closed, toggles the value
of clink_mute.
Clink to Mics Mute Maps the mute of the HDX codec to mute “Mics” on
SoundStructure when all microphones are to be muted
Clink Mute Link 1 to 2
Clink Mute Link 2 to 1
…
If there are multiple SoundStructure devices in a design,
there will be events to synchronize the clink_mute state
of each device to the next device and from the last device
to the first device.
Push-to-mute Table Mic Button Event This event maps the value of the digital_gpio_state of the
button inversely to the mute state of the microphone.
While the microphone switch is closed
(digital_gpio_state=0), the microphone is muted
(mute=1). While the microphone switch is open
(digital_gpio_state=1), the microphone is muted
(mute=0).
Push-to-talk Table Mic Button Event This event maps the value of the digital_gpio_state of the
button directly to the mute state of the microphone.
While the microphone switch is closed
(digital_gpio_state=0), the microphone is unmuted
(mute=0). While the microphone switch is open
(digital_gpio_state=1), the microphone is muted
(mute=1).
Logic Output Mode Event Name Description
Activate on Mute Table Mic LED Event This event maps the mute state of the microphone
directly to the digital_gpio_state of the LED. If the
microphone is muted (mute=1) then the LED is turned
on (digital_gpio_state=1).
