Fig. 85 Real-time output structure in pulse mode 0
(2) Pulse mode 1
When the pulse output mode select bit is set to “1”, the microcom-
puter enters pulse mode 1, and a pulse output port pins are sepa-
rately controlled (6 bits and 2 bits).
Figures 86 shows the real-time output structure in pulse mode 1.
When the waveform output select bits are set to “01” (bit 1 = “0” and
bit 0 = “1”), RTP13 to RTP10, RTP03, and RTP02 become program-
mable I/O port pins. Simultaneously, RTP01 and RTP00 become
pulse output port pins.
When the waveform output select bits are set to “10” (bit 1 = “1” and
bit 0 = “0”), RTP13 to RTP10, RTP03, and RTP02 become pulse out-
put port pins. At this time, RTP01 and RTP00 become programmable
I/O port pins.
When the waveform output select bits are set to “11” (bit 1 = bit 0 =

“1”), pulse output port pins are divided into two groups; one consists
of RTP13 to RTP10, RTP03, RTP02 and the other consists of RTP01
and RTP00.
When the waveform output select bits are set to “00” (bit 1 = bit 0 =
“0”), port P5 pins become normal programmable I/O port pins.
RTP13 to RTP10, RTP03, and RTP02 are controlled by timer A2.
Also, RTP01 and RTP00 are controlled by timer A0.
The contents of the pulse output data register 1 (high-order 6 bits at
address A416), which corresponds to RTP13 to RTP10, RTP03, and
RTP02, are output to this port each time when the contents of timer
A2 counter becomes “000016”. The contents of the pulse output data
register 0 (low-order 2 bits at address A216), which corresponds to
RTP01 and RTP00, are output to this port each time when the con-
tents of timer A0 counter become “000016”.
