7.1.4.5 Band limit: BLFLAG
7.2 Interrupt line
The level voltage reflects the field strength received by the antenna. The level voltage is
analog-to-digital converted with 4 bits and output via the control interface. This 4-bit level
value can be compared to a threshold level set by the SSL bits (see
ADC (which converts the analog value to digital) is triggered by a search or preset cycle.
During a tuning step, which can be a search or a preset it is triggered by these algorithms
and compares the level with the threshold set by the SSL bits. The LEVFLAG bit is set if
the RSSI level drops below the threshold level set by the SSL bits (see
interrupt is only generated if the corresponding mask bit is set.
The frequency ready flag bit FRRFLAG is set to logic 1 when the automatic tuning has
finished a search or preset. The description of this bit is given in
cleared by a read of the flag register.
The band limit bit BLFLAG is set to logic 1 when the automatic tuning has detected the
end of the tuning band. This bit is described in
flag register.
The interrupt line driver is a MOS transistor with a nominal sink current of 900 A. It is
pulled HIGH by an 18 k resistor connected to pin VREFDIG. The interrupt line can be
connected to one other similar device with an interrupt output and an 18 k pull-up
resistor, providing a wired-OR function. This allows any of the drivers to pull the interrupt
line LOW by sinking the current (see
generates an interrupt.
