-EXAMPLE OF BUS DATA TRANSMITTER-
S : Start
ADR : Address Byte
DIV1 : Divider Byte 1 (frequency data)
DIV2 : Divider Byte 2 (frequency data)
CONT : Control Byte
BAND : Band SW Byte
A : Acknowledge
P : Stop
[1] Transmitter - 1
[2] Transmitter - 2
[3] Transmitter – 3 (This can be applies if control data and bandswitch data have already been programmed.)
[4] Transmitter – 4 (This can be applies if frequency data have already been programmed.)
[5] Transmitter – 5 (This can be applies if frequency data and bandswitch data have already been programmed.)
Until the I²C-bus STOP Condition is detected, it is possible to input the additional data without transmitting the address
data again. (For example: Frequency sweep is possible with additional frequency data.)
If data transmission is aborted, data programmed before the abort are valid.
