Fig. 57 Bit configuration of pulse output data registers 1 and 0 in
pulse output port mode 1
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 RTP23, RTP22, RTP21, and RTP20 become the pulse output ports
(RTP2 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 RTP33, RTP32, RTP31, RTP30 become the pulse output ports
(RTP3 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 RTP33, RTP32, RTP31, RTP30
Four of RTP23, RTP22, RTP21, RTP20.
Each time the contents of timer A8 counter become 000016, the con-
tents of the pulse output data register 1 (address A416)’s high-order
4 bits (bits 7 to 4), which corresponding to RTP33, RTP32, RTP31,
RTP30, are output from ports.
Each time the contents of timer A5 counter become 000016, the con-
tents of pulse output data register 0 (address A216)’s low-order 4 bits
(bits 3 to 0), which corresponding to RTP23, RTP22, RTP21, RTP20,
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 RTPTRG1 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 RTP23,
RTP22, RTP21, and RTP20. Because timer A6 is used for pulse
width modulation, actuate timer A6 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 A5 counter become 000016.
The pulse width modulation using timer A6 can be applied by setting
the pulse width modulation enable bit 0 of the pulse output data reg-
ister 1 (bit 0 at address A416) to “1” and the pulse width modulation
timer select bits of the pulse output control register (bits 5 and 4 at
address A016) to “00”. Figure 58 shows example waveforms in pulse
mode 0.
In ports selecting pulse mode 0, output of RTP33, RTP32, RTP31
and RTP30 is controlled by the waveform output control bit 0 (bit 6)
of pulse output control register; output of RTP23, RTP22, RTP21 and
RTP20 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 P4OUTCUT.
