RUN ONCE COMMAND
Programmed blinking sequence is performed once after Run Once command. Four rising edges of CTRL signal within command
entering period is interpreted as Run Once command. If CTRL is kept high after command entering period the programmed blinking
sequence starts right after the blank period has elapsed. CTRL signal must stay high as long as programmed blinking sequence
is executed. If CTRL is set low during execution of blinking sequence, device goes to standby and execution of blinking sequence
is stopped.

If CTRL signal is low after command entering period, Run Once command is executed once the CTRL is set high.

TRAINING START COMMAND
Blinking sequence is programmed into memory in training mode. Blinking sequence is stored into volatile memory, thus removing
input voltage V
resets the memory. Memory can also be reset by giving Training Start and Training End commands without any
valid LED ON/OFF times.
LP5522 enters to Training mode after Training Start command. Two rising edges within command entering period is interpreted
as the Training Start command. The first LED ON time capturing is started once the rising edge of CTRL signal is detected after
the blank period. LED output follows CTRL signal during the programming.
The first LED ON time is recorded once CTRL signal is set low. Same time the first LED OFF time capturing is started. Programmed
blinking sequence can have one to three LED ON/OFF times. In order to be programmed correctly, at least one valid LED ON and
LED OFF time must be recorded.
