21.3.6 Parallel Real-Time Port Output Mode (Group 2 and 3)

The OUTCij pin outputs the value set by the GiRTP register in one-byte units when the value of the base

timer matches that of the GiPOj register (i=2 to 3, j=0 to 7). Table 21.15 lists specifications of the parallel

RTP output mode. Figure 21.30 shows a block diagram of the parallel RTP output function. Figure 21.31

shows an example of the parallel RTP output mode operation. (See Figure 21.7 for the G2BCR1 register

and Figure 21.8 for the G3BCR1 register.)

Item

Specification

Waveform Output Start Condition

The IFEj bit in the GiFE register (i=2 to 3, j=0 to 7) is set to "1" (channel j function

enabled)

Waveform Output Stop Condition

The IFEj bit is set to "0" (channel j function disabled)

Interrupt Request

The POijR bit in the interrupt request register is set to "1" when value of the

base timer matches that of the GiPOj register (000016 to FFFF16(1)). (See

Figure 10.14.)

Selectable Function

• Default value set function: Set starting waveform output level

• Inverse output function: Waveform output level is inversed and output from

the OUTCij pin

NOTES:

1. Set the GiPO0 register to 000116 to FFFD16 when setting the base timer to "000016" (the RST1 bit in the GiBCR1
