TDA6403; TDA6403A
I2C-bus mode (SW = GND)
WRITE MODE; R/W = 0 (see Tables 3 and 4)
Data bytes can be sent to the device after the address
transmission (first byte). Four 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 + 4 data bytes).
The device can also be partially programmed providing
that the first data byte following the address is divider
byte 1 (DB1) or control byte (CB). The bits in the data
bytes are defined in Tables 3 and 4. The first bit of the first
data byte transmitted indicates whether frequency data
(first bit = 0) or control and band-switch 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) and the band-switch register
is loaded after the 8th clock pulse of the band switch byte
(BB).
I2C-BUS ADDRESS SELECTION
The module address contains programmable address bits
(MA1 and MA0) which offer the possibility of having
several synthesizers (up to 4) in one system by applying a
specific voltage on the CE input. The relationship between
MA1 and MA0 and the input voltage applied to the CE
input is given in Table 6.
