This fields selects TrON output state, and it is effective when

external Vbus input is "H" level (5V). If external Vbus input is "L",

these bits can be set but TrON output does not operate.

Write/Read "0"

When CPU write "1" to WKUP for remote wake-up, M66290A outputs

K-State for 10ms, and return to Bus Idle-State.

(Remote wake-up signal)

This bit returns to "0" automatically after suspend is canceled.

If "1" is written into this bit after detected suspend, bus idle state is kept

for 2ms and after then shifts to K state output.
