SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
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 RTP1
3
, RTP1
2
, RTP1
1
, and RTP1
0
become the pulse output
ports with RTP1 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 RTP0
3
, RTP0

become the pulse output ports
with RTP0 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 with RTP1
and RTP0 selected:
Four of RTP1

Each time the contents of timer A1 counter become 0000

, the
contents of pulse output data register 1 (low-order 4 bits at address
1C
16
) corresponding to RTP1
3
, RTP1
2
, RTP1

, RTP1

are output
from ports.
Each time the contents of timer A0 counter become 0000
16
, the
contents of pulse output data register 0 (low-order 4 bits at address
1D
16
) corresponding to RTP0
3
, RTP0
2
, RTP0
1
, RTP0
0
are output
from ports.
When writing “0” to the specified bit of pulse output data register, “L”
level is output from the pulse output port when the contents of cor-
responding timer counter become 0000
16
; when writing “1” to it, “H”
level is output from the pulse output port.
Note :
Only when bit 5 of the particular function select register 1
(in Fig. 15) is set to “1”, this register’s contents can be
changed from the status after reset (in Fig.76).
