Fig. 51 Bit configuration of three-phase output data registers 1 and
0 in pulse output port mode 0
Pulse mode 0
This mode divides a pulse output port into 4 bits and 4 bits and indi-
vidually controls them.
When setting the pulse output mode select bit to “0”, and setting bits
2 and 1 to “0” and bit 0 to “1” of the waveform output select bits, four
of RTP03, RTP02, RTP01, and RTP00 become the pulse output ports
(RTP0 selected).
When setting the pulse output mode select bit to “0”, and setting bits
2 and 0 to “0” and bit 1 to “1” of the waveform output select bits, four
of RTP13, RTP12, RTP11, RTP10 become the pulse output ports
(RTP1 selected).
When setting the pulse output mode select bit to “0”, and setting bit 2
to “0” and bits 1 and 0 to “1” of the waveform output select bits, the
following two groups become the pulse output ports:
Four of RTP13, RTP12, RTP11, RTP10
Four of RTP03, RTP02, RTP01, RTP00.
Each time the contents of timer A3 counter become 000016, the con-
tents of three-phase output data register 1 (address A916)’s high or-
der 4 bits, (bits 7 to 4), which corresponding to RTP13, RTP12,
RTP11, RTP10, are output from ports.
Each time the contents of timer A0 counter become 000016, the con-
tents of three-phase output data register 0 (address A816)’s low or-
der 4 bits (bits 3 to 0), which corresponding to RTP03, RTP02,
RTP01, RTP00, are output from ports.
When writing “0” to the specified one of the pulse output data bits, “L”
level is output from the pulse output port when the contents of the
corresponding timer counter become 000016; when writing “1” to it,
“H” level is output from the pulse output port.
In the case that an input trigger of pin RTPTRG0 is selected, the data
written to the pulse output data bit is output from the corresponding
pulse output port by this selected trigger.
Additionally, pulse width modulation can be applied for RTP03,
RTP02, RTP01, and RTP00. Because timer A1 is used for pulse
width modulation, actuate timer A1 in the pulse width modulation
mode. When any of pulse output data bits is “1”, the pulse to which
pulse width modulation has been applied is output from the pulse
output port when the contents of timer A0 counter become 000016.
The pulse width modulation using timer A1 can be applied by setting
the pulse width modulation enable bit 0 of the three-phase output
data register 1 (bit 0 at address A916) to “1” and the pulse width
modulation timer select bits of the waveform output mode register
(bits 5 and 4 at address A616) to “00”. Figure 52 shows example
waveforms in pulse mode 0.
In ports selecting pulse mode 0, output of RTP13, RTP12, of RTP11
and RTP10 is controlled by the waveform output control bit 0 (bit 6)
of waveform output mode register; output of RTP03, RTP02, RTP01
and RTP00 is done by the waveform output control bit 1 (bit 7).
When setting the waveform output control bit to “1”, waveform is out-
put from the corresponding port. When clearing that bit to “0”, wave-
form output from the corresponding port stops, and the port
becomes floating. The waveform output control bits are cleared to “0”
by reset or by executing instructions.
Also, the waveform output control bit 1 can be cleared to “0” by in-
putting a falling edge to pin P6OUTCUT.
