RDS Interrupt Enable.
0 = Disable Interrupt (default).
1 = Enable Interrupt.
Setting RDSIEN = 1 and GPIO2[1:0] = 01 will generate a 5 ms low pulse on GPIO2 when
the RDSR 0Ah[15] bit is set.
Seek/Tune Complete Interrupt Enable.
0 = Disable Interrupt (default).
1 = Enable Interrupt.
Setting STCIEN = 1 and GPIO2[1:0] = 01 will generate a 5 ms low pulse on GPIO2 when
the STC 0Ah[14] bit is set.
Reserved.
Always write to 0.
RDS Enable.
0 = Disable (default).
1 = Enable.
De-emphasis.
0 = 75 µs. Used in USA (default).
1 = 50 µs. Used in Europe, Australia, Japan.
AGC Disable.
0 = AGC enable (default).
1 = AGC disable.
Reserved.
Always write to 0.
Sets the RSSI range for stereo/mono blend.
00 = 31–49 RSSI dBµV (default).
01 = 37–55 RSSI dBµV (+6 dB).
10 = 19–37 RSSI dBµV (–12 dB).
11 = 25–43 RSSI dBµV (–6 dB).
ST bit set for RSSI values greater than low end of range.
General Purpose I/O 3.
00 = High impedance (default).
01 = Mono/Stereo indicator (ST). The GPIO3 will output a logic high when the device is in
stereo, otherwise the device will output a logic low for mono.
10 = Low.
11 = High.
