8.2 I
No default settings at power-on reset. I
IC.
Data sequence: address, byte 0, byte 1, byte 2, byte 3, byte 4 and byte 5.
The data transfer has to be in this order. The LSB of the address being logic 0 indicates a
write operation.
Bit 7 of each byte is considered the MSB and has to be transferred as the first bit of the
byte.
The data becomes valid at the output of the internal latches with the acknowledge of each
byte. A STOP condition after any byte can shorten transmission times.
When writing to the transceiver by using the STOP condition before completion of the
whole transfer:
For new frequency setting, in both AM and FM mode, the programmable divider is
enabled by setting bit PRESET to logic 1. To select a frequency, two I
transmissions are necessary:
At 40 C the start of the acknowledge bit after transmitting the slave address exceeds the
general requirement of t
the full temperature range from 40 C to +85 C. This will not influence the overall
system performance, because the required set-up time t
condition.

If the transfer of a byte is not completed, this byte is lost and the previous information
is available.
First: bit PRESET = 1
Second: bit PRESET = 0.
