21.3 Waveform Generation Function

Waveforms are generated when the value of the base timer matches the GiPOj register (i=0 to 3; j=0 to 7).

The waveform generation function has the following six modes :

• Single-phase waveform output mode (group 0 to 3)

• Phase-delayed waveform output mode (group 0 to 3)

• Set/Reset waveform output (SR waveform output) mode (group 0 to 3)

• Bit modulation PWM output mode (group 2 and 3)

• Real-time port output (RTP output) mode (group 2 and 3)

• Parallel real-time port output (parallel RTP output) mode (group 2 and 3)

Table 21.7 lists pin settings of the waveform generation function. Table 21.8 lists registers associated with

the waveform generation function.

NOTES:

1. This port is provided in the 144-pin package only.

2. When the CAS bit in the GiBCR1 register is set to "1" (32-bit time measurement function), the OUTC1j pin (j=0 to 7)

outputs a waveform and the OUTC0k pin (k=0, 1, 4, 5), set as above, outputs a 16-bit low-order waveform.
