Specification, December 1999
In the data portion of the telegram during a WRITE operation, the MSB bit of the
first or third data byte determines whether a divider ratio or control information
is to follow. In each case the second byte of the same data type has to follow
the first byte.
If the address byte indicates a READ operation, the PLL generates an acknowl-
edge and then shifts out the status byte onto the SDA line. If the processor gen-
erates an acknowledge, a further status byte is output; otherwise the data line
is released to allow the processor to generate a stop condition. The status word
consists the lock flag and the power-on flag.
Four different chip addresses can be set by appropriate DC level at pin AS (see
While applying the supply voltage, a power-on reset circuit prevents the PLL
from setting the SDA line to LOW, which would block the bus. The power-on
reset flag POR is set at power-on and when VCC falls below 3.2 V. It will be reset
at the end of a READ operation.
