data or 1-bit data
Start pulse
(1) RL = High
6-bit RGB
The start pulse input is from STHL; the carry output, from STHR. Apart from that, operation is the same
as for RL = High.
Driver A starts latching data one FY cycle after receiving a start pulse (STHR).
It asserts the carry signal (STHL) one FY cycle before latching the last data and then stopping.
MODE1 = High (360 outputs): 119 FY cycles
MODE1 = Low (324 outputs): 107 FY cycles
Cascade Connection
Driver B starts latching data one FY cycle after receiving the carry signal (STHL) from driver A.
Note: Although the carry signal (STHL) pulses are two FY cycles long, only the first cycle counts.
The next driver treats the two cycles as a single pulse.
