The APU oscillator (X2) is in region 3C of the jwdonal schematic

The APU oscillator (X2) is clocked at 24.6 MHz, slightly faster than the master clock.

  • Side 1 is XTALO, connected to pin 45 of the S-DSP and C72.
  • Side 2 is XTALI, connected to pin 46 of the S-DSP and C71.

It is not connected to anything else. XTAL stands for "crystal." It does not clock the S-SMP directly.
