When use external clock of 48MHz, set to PLL disable.
00 : 1/1 division (external 48MHz input)
10 : 1/2 division (external 24MHz input)
01 : 1/4 division (external 12MHz input)

In suspend state, resume signal can be received even if USB
transceiver disabled.
X0 : TrON port ="Hi-Z"
01 : TrON port ="L"
11 : TrON port ="H"
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.
