SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER FLASH MEMORY VERSION
MITSUBISHI MICROCOMPUTERS

REAL-TIME OUTPUT
Each of these microcomputers is equipped with the 8-bit real-time
output function.
Whether to use the real-time output function is decided by the wave-
form output select bits of the 8-bit real-time output control register
(bits 0 and 1 at address A0
16
). (See Figure 96.) Also, the real-time
output controlled by the pulse output mode select bit of the real-time
output control register (bit 2 at address A0
16
) and is used in one of
the following ways:
4 bits
2 channels
6 bits
1 channel + 2 bits
1 channels
(1) Pulse mode 0
When the pulse output mode select bit is cleared to “0”, the micro-
computer enters pulse output port is controlled by 2 groups of 4 bits.
Figures 97 and 98 show the pulse output data register 0/1 (address
A2
16
/A4
16
) bit configuration and real-time output structure in pulse
mode 0, respectively.
When the waveform output select bits are set to “01” (bit 1 = “0” and
bit 0 = “1”), RTP0
3
to RTP0
0
become pulse output port pins, in other
words, RTP0 is selected.
When the waveform output select bits are set to “10” (bit 1 = “1” and
bit 0 = “0”), RTP1
3
to RTP1
0
become pulse output port pins, in other
words, RTP1 is selected.
When the waveform output select bits are set to “11” (bit 1 = “1” and
bit 0 = “1”), two groups consisting of RTP1
3
to RTP1
0
and RTP0
3
to
RTP0
0
become pulse output port pins, in other words, RTP1 and
RTP0 are selected.
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.
The contents of the pulse output data register 1 (high-order 4 bits at
address A4
16
), which corresponds to RTP1
3
to RTP1
0
, is output to
these ports each time when the contents of timer A1 counter be-
comes “0000
16
”. The contents of the pulse output data register 0

A0 counter becomes

When
0
is written to a specified bit of the pulse output data register,
a low-level signal is output to a pulse output port if the counter con-
tents of the timer which corresponds to the bit becomes
0000
16
:
when
1
is written to the bit, a high-level signal is output to a pulse
output port which corresponds to the bit at the same timing.
