Technical Note
[BD8132FV]
● Serial communications
The serial data control block consists of a register that stores data from the LATCH, CLK, and SDIN pins, and a DAC circuit
that receives the output from this register and provides adjusted voltages to other IC blocks.
When the IC's power supply is activated, the reset function operates to set the register to a preset value. The first bit is for
testing use only and should always be set to 0. The next bit is used to select the OSC mode. Inputting a value of 0 selects
internal frequency mode and uses a frequency of 80 kHz. Entering a value of 1 selects external frequency mode. Input an
external clock signal from the OSC pin.

(1) Serial communications timing
The 17-bit serial data input from the SDIN pin is read into the shift register using the rising edge of the signal input to the
CLK pin. This data is then loaded to the DAC register using the rising edge of the signal input to the LATCH pin.
If the data loaded into the shift register while the LATCH pin is low consists of less than 17 bits, the loaded data is
discarded. If the data exceeds 17 bits, the last 17 bits to be loaded are treated as valid.
