NOTE:
NOTES:
1. Read and write this register in 16-bit units.
1. Read-modify-write instructions cannot be used to set the DTT register. Refer to Usage Notes for details.
2. The DTT register setting is enabled when the INV15 bit in the INVC1 register is set to 0 (dead time enabled). No dead time is
3. The INV16 bit in the INVC1 register determines the start trigger of the DTT register. The INV12 bit determines the count source.

If a setting value is n, f1 is divided by n+1.
Timers A1, A2, and A4 start every time timer B2 underflows.
This one-shot timer is used to delay the timing for a turn-on signal
to be switched to its active level in order to prevent the upper and
lower arm short circuit.
If a setting value is n, the count source is counted n times after the
start trigger occurs, and then the timer stops.
