Oscillator Stabilization Time After Standby Mode Is Cleared - Renesas H8/38024 Hardware Manual

5.3.3

Oscillator Stabilization Time after Standby Mode is Cleared

Bits STS2 to STS0 in SYSCR1 should be set as follows.
Note that stabilization times for the H8/38024, H8/38024S, and H8/38024F-ZTAT Group and for
the H8/38124 Group are different.
• When a oscillator is used
The table below gives settings for various operating frequencies. Set bits STS2 to STS0 for a
wait time at least as long as the oscillation stabilization time.
