<R>
(1) TMQ1 dead-time compare register (TQ1DTC)
(2) Dead-time counters 1 to 3
The TQ1DTC register is a 10-bit compare register that specifies a dead-time value.
Rewriting this register is prohibited when the TQ1CTL0.TQ1CE bit = 1.
This register can be read or written in 16-bit units.
Reset sets this register to 0000H.
Caution To generate the dead-time period, set the TQ1DTC register to 1 or more.
The dead-time counters are 10-bit counters that count dead time.
These counters are cleared or count up at the rising or falling edge of the TOQ1m output signal by TMQ1, and
are cleared or stopped when their count value matches the value of the TQ1DTC register. The count clock of
these counters is the same as that set by the TQ1CTL0.TQ1CKS2 to TQ1CTL0.TQ1CKS0 bits of TMQ1.
Remarks 1. The operation differs when the TQ1OPT2.TQ1DTM bit = 1. For details, see 9.4.2 (4) Automatic
TQ1DTC
After reset: 0000H
2. m = 1 to 3
When the operation is stopped (TQ1CTL0.TQ1CE bit = 0), the dead-time period is not
generated and the output level of the TOQ1T1 to TOQ1T3 pins and TOQ1B1 to TOQ1B3 pins
will be in the initial status. For the system protection, therefore, before operation is being
stopped, set the TOQ1T1 to TOQ1T3 and TOQ1B1 to TOQ1B3 pins to the high impedance
state, or set the output level of pins and switch them to the port mode.
If a dead time period is not needed, set the TQ1DTC register to 0.
