7 FUNCTIONAL DESCRIPTION
The device is controlled via the I²C-bus. For programming,
a module address of 7 bits and the R/W bit for selecting the
read or the write mode is required.
7.1 Write mode
Data bytes can be sent to the device after the address
transmission (first byte). Seven data bytes are needed to
fully program the device. The bus transceiver has an
auto-increment facility, which permits the programming of
the device within one single transmission (address + 6
data bytes).
The device can also be partially programmed providing
that the first data byte following the address is the first
divider byte DB1 or the control byte CB. The data bytes
are defined in Tables 2 and 3.
The first bit of the first data byte indicates whether
frequency data (first bit = 0) or control, port and auxiliary
data (first bit = 1) will follow. Until an I²C-bus STOP
command is sent by the controller, additional data bytes
can be entered without the need to re-address the device.
The frequency register is loaded after the 8th clock pulse
of the second divider byte DB2, the control register is
loaded after the 8th clock pulse of the control byte CB, the
band switch register is loaded after the 8th clock pulse of
the band switch byte BB and the auxiliary register is
loaded after the 8th clock pulse of the auxiliary byte AB.
To program the AGC take-over point setting and the AGC
current to a different value than the default value, an
additional byte, the auxiliary byte, has to be sent. To this
end, the auxiliary byte is preceded by a control byte with
the test bits T2, T1 and T0 set to 011 (see Table 5).
