Note: This function must be used in combination with interrupt skipping.
When interrupt skipping is disabled (the T3AEN and T4VEN bits in the timer interrupt
skipping set register (TITCR) are cleared to 0 or the skipping count set bits (3ACOR and
4VCOR) in TITCR are cleared to 0), make sure that A/D converter start requests are not
linked with interrupt skipping (clear the ITA3AE, ITA4VE, ITB3AE, and ITB4VE bits in
the timer A/D converter start request control register (TADCR) to 0).
