Control Interface Operational Description
LP5522 has one digital control input, CTRL. Threshold levels of CTRL input are fixed to enable control from low voltage controller.
CTRL signal is used to control the mode of the circuit. A rising edge of the CTRL signal activates the circuit and starts a command
entering period. During the command entering period all rising edges are counted. After command entering period there is a blank
period when no rising edges are allowed. If CTRL is left high after command entering period, the consequent command is performed
right after the blank period.
Note that timing diagrams are not on scale!

If CTRL signal is low after command entering period, command execution starts when CTRL is pulled high. This does not apply to
Run command. With Run command CTRL must be high. Note that no rising edges are allowed during blank period.
