RDS DEMODULATOR (Cont’d)

RDS DE3

—

Address 005E h

Reset Value: xxxx x000b

b7-3 = reserved.

b2 = ARI

ARI indicator.

0 = pure RDS, no ARI (Reset Value)

1 = RDS plus ARI.

Note that this bit is simply an indicator.

b1 = AREN

Selects software or hardware ARI indication.

0 = internally by hardware (Reset Value)

1 = forced by software according to ARP bit.

b0 = ARP

Preset ARI indication.

0 = ARI (Reset Value)

1 = pure RDS without ARI.

RDS DE4

—

Address 005F h

Reset Value: 0xx0 0000b

b7 = DETM

Selects test mode when set to “1”. This bit must be

kept in the reset state (“0”) for normal operation.

b6-5 = reserved.

b4-1 = TE4-TE1

RESERVED. These bits are for internal test use

only: they must be kept in the reset state (all “0”)

for normal operation

b0 = NDEPOR

Enables the module

0 = module disabled (Reset Value)

1 = module enabled (normal operating mode).
