Product specification
RDS/RBDS pre-processor
SAA6588
I
2
C-
BUS INTERFACE REGISTERS
The I
2
C-bus interface is connected to other blocks of the
pre-processor via internal registers (byte oriented). Those
can either be written by the pre-processor control and read
by the main controller I
2
C-bus or vice versa.
The device provides 3 input control registers to which may
be written via the I
2
C-bus and 7 output registers which
may be read via the I
2
C-bus.
The decoder control updates the output registers after the
detection of a new RDS/RBDS information block and
reads the new mode control settings of the input control
registers. Both operations may occur in the same time slot,
provided that the read operation is complete before a new
RDS/RBDS data bit is processed by the demodulator.
For the corresponding access the registers are addressed
by two separate register pointers, write-enable and
read-enable signals, which are activated either via the
decoder control or via the I
2
C-bus interface control.
During a read or write transmission from the I
2
C-bus the
read/write pointer selects the register of the first byte for
transmission and is auto-incremented by the I
2
C-bus
control for the transfer of subsequent bytes.
During a write transmission after reception of the device
slave address and write bit, the mode control settings for
the pre-processor have to be send in the protocol
sequence as shown in Table 1 and Fig.5.
During a read cycle after reception of the device slave
address and read bit the requested RDS/RBDS data has
to be received in the protocol sequence as given in Table 2
and Fig.7.
