Port HS Data Bits—Data registers or routed timer outputs or routed PWM outputs
These register bits can be used to control the high-side driver gates if selected as control source. See PIM section
for routing details.
If the associated HSEx bit is set to 0, a read returns the value of the Port HS Data Register (HSDRx).
If the associated HSEx bit is set to 1, a read returns the value of the selected as gate control source.
When entering in STOP mode the Port HS Data Register (HSDRx) is cleared.
0 High-side driver gate is turned off
1 High-side driver gate is turned on

After enabling the high-side driver with the HSEx bit in HSCR
register, the user must wait a minimum settling time t
before turning on the high-side driver gate.
