PULSE OUTPUT PORT MODE
Figure 48 shows the block diagram in the pulse output port mode.
This mode has a 6-bit pulse output port. The waveform output select
bits (bits 0 to 2) of waveform output mode register (address A616)
select use of pulse output port. The 6-bit pulse output port can also
be divided into 4 bits and 2 bits with the pulse output mode select bit
(bit 3) of waveform output mode register (address A616); each of
them can be individually controlled.
Set timers A3 and A0 to the timer mode because they are used in the
pulse output port mode. Figure 50 shows the bit configuration of
timer A3 and A0 mode registers in the pulse output port mode.
Timers A3 and A0 start count when setting the corresponding timer
count start bit to “1”, and they stop it when clearing that bit to “0”.
Fig. 48 Block diagram in pulse output port mode
Each bit using timer A0 as a trigger can also be controlled by an in-
put trigger from pin RTPTRG0. This control is selected by the pulse
output trigger select bits of the three-phase output data register 0
(bits 7 and 6 at address A816). Also, this externally-input trigger can
be selected from the following three types: falling edges, rising
edges, and falling and rising edges.
The reversed content of the pulse output data bit can be output to
each pulse output port by the pulse output polarity select bit of the
three-phase output data register 1 (bit 3 at address A916). When the
pulse output polarity select bit = “0”, the content of the pulse output
data bit is output as it is; when the pulse output polarity select bit =
“1”, the reversed content is output.
