18.8 AT^SAIC

s

2	Selects the earpiece amplifier 2
3	Selects both amplifiers. Note that both amplifiers are connected in parallel and
	therefore, get the same output power if <ep>=3.

<clock>(num)(^SNFW)

Parameter is mandatory if <io>=1 (digital).

0	256kHz clock
1	512kHz clock

<mode>(num)(^SNFW)

Parameter is mandatory if <io>=1 (digital).

0	Master mode
1	Slave mode

<frame_mode>(num)(^SNFW)

Parameter is mandatory if <io>=1 (digital).

0	Short frame
1	Long frame

Notes

•The factory defaults of AT^SAIC vary with the selected audio mode. If AT^SNFS=1 or 4 or 5, then AT^SAIC=2,1,1,0,0,0.

If AT^SNFS=2 or 3 or 6, then AT^SAIC=2,2,2,0,0,0. AT^SNFD can be used to reset the factory defaults.

•For use after restart of the ME, you are advised to store the settings of AT^SAIC and AT^SNFS to the audio profile saved with AT^SNFW. Otherwise, audio mode 1 (AT^SNFS=1) and audio interface 2 (AT^SAIC=2,1,1) will be active each time the ME is powered up.

•The parameters <clock>, <mode> and <frame_mode> are mandatory, if parameter <io> is set to 1 (digi- tal). These parameters can be used to configure the PCM functionality over the digital audio interface (DAI). The PCM interface supports master or slave mode, short frame or long frame synchronization and 256 kHz or 512 kHz bit clock frequency. In slave mode the clock frequency setting has no influence, because of the BCLKIN signal being directly used for data shifting. The setting may therefore be either 0 or 1. The table below lists possible configuration combinations.

Configuration	<clock>	<mode>	<framemode>
Master, 256kHz, short frame	0	0	0
Master, 256kHz, long frame	0	0	1
Master, 512kHz, short frame	1	0	0
Master, 512kHz, long frame	1	0	1
Slave, 256kHz, short frame	0 or 1	1	0
Slave, 256kHz, long frame	0 or 1	1	1
Slave, 512kHz, short frame	0 or 1	1	0
Slave, 512kHz, long frame	0 or 1	1	1
