Art Chip HT1618

This pin inputs serial data at the rising edge of the shift clock (starting from the lower bit) This pin outputs serial data at the falling edge of the shift clock (starting from the lower bit ) STB Serial Interface Strobe This pin reads initialization serial data at the rising/falling edge of the shift clock then wait for the command. The data input after the STB has fallen is processed as a command.
