Rev. 0.3
audio options (FM example):

AUDIO_MODE bits selects one of the audio output modes: (0) digital volume mode, (1) bass/treble
mode, (2) bass/treble with volume control mix mode 1, (3) bass/treble with volume control mix mode 2.

ADJPT_ ATTN bit specifies if the 100 kHz adjacent points have audio output attenuated by 2 dB or not.

ADJPT_STEO bit specifies if the 100 kHz adjacent points have stereo indicator and stereo separation.

FM_MONO bit specifies if FM audio output is forced mono or stereo.
8. Optionally, the system controller can issue the SET_PROPERTY command to change the receive volume,
bass/treble level, FM de-emphasis, soft-mute, and banding properties to override the default settings.
*Note:
If pin 1 of the Si4822/26/40/44 SSOP24 packaged ATDD devices has been pulled up by the resistor, it is forced to use
default band properties. The system controller-specified band properties (i.e., band top, band bottom, channel space,
FM de-emphasis, FM blend RSSI mono thresholds) will be ignored and have no effects.
5.2.2. Band Switch Sequence
1. Depends on system controller wants to switch to the new band within the same band mode across different
band modes.
2. If system controller wants to switch band within same band mode, it can directly issue the power up
command as in step 3. Otherwise, it needs to reset ATDD device first and wait till IRQ is received to power
up the ATDD device again.
3. System controller issues ATDD_POWER_UP command with the bulleted arguments below to power up
the device:

Set ARG1 bit[5:0] BANDIDX band index to the desired band number.

Set ARG1 bit[7] XOSEN bit = 1 if a 32.768 kHz crystal is in use. Set ARG1 bit[6] XOWAIT bit =0 if typical 600 ms
crystallization time is enough or set the XOWAIT bit = 1 for a longer time of 900 ms.

Optionally include ARG2 ARG3* if new band bottom frequency is different from default.

Optionally include ARG4 ARG5* if new band top frequency is different from default.

Optionally include ARG6* if new band channel space is different from default (AM).

Optionally include ARG7 for new features of Si4827 and Si4844B devices.
4. System controller waits till IRQ is received for the tune wheel frequency ready.
5. System controller issues ATDD_GET_STATUS command to obtain the latest status for display:

If REPLY0 bit[4] INFORDY bit = 1, i.e. info ready, the host can read and display the status, such as the band mode,
station, and stereo states.

The tune frequency is ready when combined frequency of REPLY2, REPLY3 is non-zero (4-digit BCD number).
6. Optionally, the system controller can issue the ATDD_AUDIO_MODE command to select one of the audio
output modes: (0) digital volume mode, (1) bass/treble mode, (2) bass/treble with volume control mix mode
1, (3) bass/treble with volume control mix mode 2 (FM example).
7. Optionally, the system controller can issue the SET_PROPERTY command to change the receive volume,
bass/treble level, FM de-emphasis, soft-mute, and banding properties to override the default settings (FM
example).
*Note:
If pin 1 of the Si4822/26/40/44 SSOP24 packaged ATDD devices has been pulled up by resistor, it is forced to use
default band properties. The system controller optionally specified band properties (i.e., band top, band bottom, channel
space, FM de-emphasis, FM blend RSSI mono thresholds) will be ignored and have no effects.
5.2.3. Power Off Sequence
1. System controller can optionally issue the POWER_DOWN command first to stop device current
operations.
2. System controller holds the ATDD device RSTb pin in low state in power off. The current consumption of
the ATDD device will be at about 10 µA at 3.3 V supply. (Note that the Si47xx DTDD device POWER_UP
commands is not supported in the ATDD device. The system controller needs to reset the device and issue
ATDD_POWER_UP command to power up.)
