Low-power AM/FM stereo radio for handheld applications
8.5 RF level information (RSSI)
For processing Receiver Signal Strength Information (RSSI) in both AM and FM modes,
the internal level voltage is analog-to-digital converted with a 4-bit ADC. The level
information can be read by bits LEV[3:0] in the read register. In autonomous search mode,
bits LEV[3:0] still indicate some momentary level information, however the data is
dependent upon the readout timing and can be considered to have no relevance to the
user. The ADC full-scale goes from 0.25 V to 0.95 V. In AM mode, the level information
covers the ADC full-scale. In FM mode, the level information does not fully cover the ADC
full-scale.
8.6 Software programmable ports
Two software programmable ports can be addressed via the bus control. These ports can
be independently switched to multiple functions, knowing:
Outputs: SWPORT1 and SWPORT2 can act as output ports which are capable of
sourcing and sinking approximately 9 mA.
Inputs: SWPORT1 and SWPORT2 can act as input ports of which the status can be
read out via bus control.
Remark: Port SWPORT2 can be switched as input for the 13 MHz reference signal. In
that case, no other functions can be programmed for this port.
