PULSE OUTPUT PORT MODE
9.2 Block description
9.2 Block description
Figure 9.2.1 shows the block diagram in the pulse output port mode. Also, the pulse-output-port-mode-
relevant registers are described below.
In the pulse output port mode and three-phase waveform mode, the following registers are used in common:
the waveform output mode register (address A616), three-phase output data register 0 (address A816), and
three-phase output data register 1 (address A916). After the pulse output port mode is set by the waveform
output select bits (bits 2 to 0 at address A616), be sure to set the relevant registers.
Note that, when not using the pulse output port mode and three-phase waveform mode, be sure to fix the
waveform output select bits (bits 2 to 0 at address A616) to “000 .”
