Remark
Recommended oscillator circuit constants may differ on the wiring capacitance of the target board
the customer designed. When using a resonator for the target system, let manufacturer evaluate.

Note 1.
The t
w(RL)
indicates a time between crystal resonator or oscillator starts to provide clock and PLL
becomes stable. The t
w(RL)
depends on the rating of crystal resonator or oscillator. At power on, the
t
w(RL)
is measured after the point that power supply voltage reaches to 0.8 V

Note that, during HALT mode, t
cC
is extended to 8 times as long as that of Active mode.
