Si4730/31-D50
For details on timing specifications and diagrams, refer
to Table 6, “3-Wire Control Interface Characteristics,” on
page 9; Figure 4, “3-Wire Control Interface Write Timing
Parameters,” on page 9, and Figure 5, “3-Wire Control
Interface Read Timing Parameters,” on page 9.
4.18. GPO Outputs
The Si4730/31 provides three general-purpose output
pins. The GPO pins can be configured to output a
constant low, constant high, or high-impedance. The
GPO pins can be reconfigured as specialized functions.
GPO2/INT can be configured to provide interrupts and
GPO3 can be configured to provide external crystal
support or as DCLK in digital audio output mode.
4.19. Firmware Upgrades
The Si4730/31 contains on-chip program RAM to
accommodate minor changes to the firmware. This
allows Silicon Labs to provide future firmware updates
to optimize the characteristics of new radio designs and
those already deployed in the field.
4.20. Reset, Powerup, and Powerdown
Setting the RST pin low will disable analog and digital
circuitry, reset the registers to their default settings, and
disable the bus. Setting the RST pin high will bring the
device out of reset.
A powerdown mode is available to reduce power
consumption when the part is idle. Putting the device in
powerdown mode will disable analog and digital circuitry
while keeping the bus active.
4.21. Programming with Commands
To ease development time and offer maximum
customization, the Si4730/31 provides a simple yet
powerful software interface to program the receiver. The
device is programmed using commands, arguments,
properties, and responses.
To perform an action, the user writes a command byte
and associated arguments, causing the chip to execute
the given command. Commands control an action such
as powerup the device, shut down the device, or tune to
a station. Arguments are specific to a given command
and are used to modify the command.
Properties are a special command argument used to
modify the default chip operation and are generally
configured immediately after powerup. Examples of
properties are de-emphasis level, RSSI seek threshold,
and soft mute attenuation threshold.
Responses provide the user information and are
echoed after a command and associated arguments are
issued. All commands provide a 1-byte status update,
indicating interrupt and clear-to-send status information.
For a detailed description of the commands and
properties for the Si4730/31, see “AN332: Si47xx
Programming Guide.”
