The Receiver Control Register configures the following:
Receiver LNA gain
Digital RSSI threshold
Receive baseband bandwidth
Valid Data Indicator response time
Function of pin 16
Bit [15..8] –
Command Code:
These bits are the command code that is sent serially to the processor that
identifies the bits to be written to the Receiver Control Register.
Bit [7..6] –
Pin 16 Func:
Selects the function of Pin 16. See Table 7 below.
Table 7.
Bit [5..4] –
Receiver LNA Gain:
These bits set the receiver LNA gain, which can be changed to
accommodate environments with high interferers. The LNA gain also affects the true RSSI value.
Refer to Bit [2..0] for RSSI. See Table 8 below for gain configuration.
Table 8.
Bit [3..1] –
Digital RSSI Threshold:
The digital receive signal strength indicator threshold may be set to
indicate that the incoming signal strength is above a preset limit. The result is stored in bit 7 of
the status register. There are eight (8) predefined thresholds that can be set. See Table 9 below
for settings.
