2. When interrupt skipping is disabled (the T3AEN and T4VEN bits are cleared to 0 in the
to section 9.4.8, Complementary PWM Mode.
timer interrupt skipping set register (TITCR) or the skipping count set bits (3ACOR and
4VCOR) in TITCR are cleared to 0)), be sure to disable link of buffer transfer with
interrupt skipping (clear the BTE1 bit in the timer buffer transfer set register (TBTER) to
0). If link with interrupt skipping is enabled while interrupt skipping is disabled, buffer
transfer will not be performed.
