SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
When writing data to the dead-time timer (address 1B16), the data is
written to the reload register shared by three dead-time timers.
When the dead-time timers catch the start trigger from the respec-
tive timers, the reload register contents are transferred to its counter
and the dead-time timer decrements with the clock source selected
by bits 6 and 7 of pulse output data register (address 1C16). Addition-
ally, this timer can accept another trigger before completion of the
preceding trigger operation. In this case, after transferring the reload
register contents to the dead-time timer at acceptance of the trigger,
the value is decremented.
The dead-time timer operates as a one-shot timer. Accordingly, this
timer starts pulse output when the trigger is caught, and finishes
pulse output and stops operation when its contents become “0016”,
and waits next trigger.

Note : Only when bit 5 of the particular function select register 1 (in Fig. 15)
is set to “1”, these registers’ contents can be changed from the status
during reset (in Fig.76).
Fig. 44 Bit configuration of pulse output data registers 1 and 0 in three-phase waveform mode
In the three-phase waveform mode, setting bit 7 of the waveform out-
put mode register (address 1A16) to “1” makes positive waveforms
__
(U, V, W phases) and their negative waveforms (U, V, W phases)
output from the respective ports. When that bit is “0”, their ports are
____
floating. That bit is cleared to “0” by inputting falling edge to the INT0
pin or reset other than clearing by an instruction..
Additionally, setting bits 5 to 3 of the pulse output data register 1 (ad-
dress 1C16) to “1” makes the corresponding positive waveforms
fixed to “H”, and setting bits 7 to 5 of the pulse output data register 0
(address 1D16) to “1” makes the corresponding negative waveforms
fixed to “H”.
____
When selecting the three-phase waveform mode, INT0 pin become
input-only pin.
