RW
Enable or disable Q0 MOSFET.
If this bit set 10, Q0 turn on function is only
valid in following conditions:
WRX_IN voltage over than WRX_INSERT
threshold and not exceed VBUS_OVP
threshold with EN pin pull low
If this bit set 11, Q0 turn on function is only
valid in following conditions :
VBUS voltage over than VBUS_INSERT
threshold with EN pin pull low.
If the device operates in bypass mode with
BEHAVIOR_AFTER_WDT bit is 1, this bit will
not be reset by WDT.
00 : Disable (Q0 turn off)
01 : Disable (Q0 turn off)
10 : Enable (Q0 turn on) (default)
11 : Enable (Q0 force turn on)
