If setting value is n , the timer stops w hen counting n times a count
1 to 255
source selected by the INV12 after start trigger occurs. Positive
or negative phase, w hich changes from inactive level to active
WO
level, shifts w hen the dead time timer stops.
NOTES :
1. Use the MOV instruction to set the DTT register.
2. The DTT register is enabled w hen the INV15 bit in the INVC1 register is set to “0” (dead time enabled). No dead time
can be set w hen the INV15 bit is set to “1” (dead time disabled). The INV06 bit in the INVC0 register determines
start trigger of the DTT register.
