*1) -VDET1 in Vaccess specification is guaranteed by design.
*2) CGout is connected between OSCIN and VSS, CDout is connected between OSCOUT and VSS.
R2051 series incorporates the capacitors between OSCIN and VSS, between OSCOUT and VSS.
Then normally, CGout and CDout are not necessary.
*3) Crystal oscillator: CL=6-8pF, R1=30K
