9.2 Block description

9.2.1 Waveform output mode register

Figure 9.2.2 shows the structure of the waveform output mode register (in pulse output port mode).

Fig. 9.2.2 Structure of waveform output mode register (in pulse output port mode)

(1) Waveform output select bits (bits 2 to 0)

These bits are used to select whether a pin serves as a programmable I/O port pin or

a pulse output pin. Table 9.2.1 lists the functions of the waveform output select bits.

Table 9.2.1 Functions of waveform output select bits

Port: This serves as a programmable I/O port pin or timer I/O pin.

RTP: This serves as a pulse output pin regardless of the contents of the corresponding port direction register.

Note: This is selected by the pulse output mode select bit (bit 3 at address A616).

When pulse mode 0 is selected,

0: RTP10, RTP11: pulse outputs are disabled.

1: RTP10, RTP11: pulse outputs are enabled.

When pulse mode 1 is selected,

fix this bit to “0.”

See Table 9.2.1.

See Table 9.2.2.

0 : Pulse mode 0

1 : Pulse mode 1

When pulse mode 0 is selected,

0 : RTP00 to RTP03: pulse outputs are disabled.

1 : RTP00 to RTP03: pulse outputs are enabled.

When pulse mode 1 is selected,

0 : RTP00 to RTP03, RTP10, RTP11: pulse outputs

are disabled.

1 : RTP00 to RTP03, RTP10, RTP11: pulse outputs

are enabled.

Note: When not using the pulse output port mode and three-phase waveform mode, be sure to fix these bits to “0002.”
