C-BUS DATA FORMAT

C-bus address selection
The address byte ADB contains programmable module
address bits MA1 and MA0 which allow up to four
synthesizers to be used in the same system, and are
configured by applying one of four possible voltages on
pin AS; see Tables 1 and 2. For each voltage on pin AS,
the resultant values of bits MA1 and MA0 are shown in
Table 3.
8.2
Write mode
The write mode is defined by setting bit R/W to logic 0 in
address byte ADB; see Table 1.
Data bytes can be sent to the device after sending the first
addressbyte.Fourdatabytesarerequiredtofullyprogram
the device.
The bus transceiver has an auto-increment facility which
allows the device to be programmed by one transmission
(address byte with 4 data bytes). The device can be
partially programmed provided that the first data byte
following the address byte is divider byte DB1 or control
byte CB.
The MSB of the first data byte DB1 indicates whether
frequency data (MSB = 0) or control and band switch data
willfollow.Additionaldatabytescanbeenteredwithoutthe
need to re-address the device until an I

command is sent by the controller.
The frequency divider register is loaded after the 8th clock
pulse of byte DB2. The control register is loaded after the
8th clock pulse of byte CB, and the band switch register is
loaded after the 8th clock pulse of byte BB.
