OHS
0
pin HSVGC is switched to input
1
pin HSVGC is switched to active output
PHS
0
polarity of signal at pin HSVGC in output mode (master mode) is active HIGH; rising
edge of the input signal is used in slave mode
1
polarity of signal at pin HSVGC in output mode (master mode) is active LOW; falling
edge of the input signal is used in slave mode
