Description
Establishes the logic sense of the digital line sync output. Setting polarity to 1 causes the
leading edge of line sync to be a low-to-high transition. Setting polarity to 0 causes the
leading edge of line sync to be a high-to-low transition. The LSPP? query returns the
current polarity of LSPP.

command
updates the hardware to the new settings and redraws the test image.

// Enable Line Sync
LSPP 1

// Make the pulse 20 pixels wide
LSPG 300
// Pulse to occur 300 lines after
// the last line of active video
