Received bit-stream has both RDS and MMBS blocks
('E' block).

Received bit-stream has RDS block only, no MMBS block
('E' block).

Description
7:5
TXCCAA[2:0]
RXCCAD[4:0]
010
Scaling factor to determine in-band noise power to out-of-band noise power
ratio. Value 0 ~ 7 directly written in, default is 2. When TXCCAA is not zero,
valid channels must satisfy the condition "in-ban power > TXCCAA * out-of-
band power", which usually is set to select channels without adjacent channel
interference. When TXCCAA=0, this condition is omitted.
4:0
0 1001
Lower 5 bits of RXCCAD [5:0]. See reg. 02h [7] for RXCCAD [5]. RXCCAD
[5:0] is used to set the threshold for RX CCA. When RSSI is selected as
RXCCA criteria (default), channel with RSSI (dBuV) > (RXCCAD-10) dBuV
is selected as valid channel. When SNR is selected as criteria for CCA, channel
with CNR at RF input > RXCCAD will be selected as valid channel.
