BUFFERING OF RDS DATA
The repetition of the RDS data is around the 1187 Hz. This
results in an interrupt on the microcontroller for every
842
s. In a second mode, the RDS interface has a double
16-bit buffer.
8.15.4
BUFFER INTERFACE
The RDS interface buffers 16 data bits. Every time 16 bits
are received, the data line is pulled down and the buffer is
overwritten. The microcontroller has to monitor the data
line in at most every 13.5 ms. This mode can be selected
via an I2C-bus.
In Fig.19 the interface signals from the RDS decoder and
the microcontroller in buffer mode are shown. When the
buffer is filled with 16 bits the data line is pulled down. The
data line will remain LOW until reading of the buffer is
started by pulling down the clock line. The first bit is
clocked out. After 16 clock pulses the reading of the buffer
is ready and the data line is set HIGH until the buffer is
filled again. The microcontroller stops communication by
pulling the line HIGH. The data is written out just after the
clock HIGH-to-LOW transition. The data is valid when the
clock is HIGH. When a new 16-bit buffer is filled before the
other buffer is read, that buffer will be overwritten and the
old data is lost.
