PULSE OUTPUT PORT MODE

7906 Group User’s Manual Rev.2.0

9-5

9.2 Block description

(2) Pulse output mode select bit (bit 3)

This bit is used to select the type of the pulse output port mode: pulse mode 0 or pulse mode 1.

(3) Pulse width modulation timer select bits (bits 5 and 4)

These bits are used to select the type of the pulse width modulation. Table 9.2.2 lists the functions

of the pulse width modulation timer select bits.

(4) Waveform output control bit 0 (bit 6)

• Pulse mode 0

When this bit is set to “1,” pulse output from pins RTP10 and RTP11 becomes enabled.

When this bit is cleared to “0,” pins RTP10 and RTP11 enter the floating state.

• Pulse mode 1

Fix this bit to “0.”

(5) Waveform output control bit 1 (bit 7)

• Pulse mode 0

When this bit is set to “1,” pulse output from pins RTP00 to RTP03 becomes enabled.

When this bit is cleared to “0,” pins RTP00 to RTP03 enter the floating state.

• Pulse mode 1

When this bit is set to “1,” pulse output from pins RTP00 to RTP03, RTP10, and RTP11 becomes

enabled.

When this bit is cleared to “0,” pins RTP00 to RTP03, RTP10, and RTP11 enter the floating state.

When a falling edge is input to pin P6OUTCUT, this bit becomes “0.” (See Figure 9.2.8.)

Table 9.2.2 Functions of pulse width modulation timer select bits

Note: The pulse width modulation cannot be applied to pins RTP10 and RTP11.
