(2) Using TO70 to TO75 as a real-time output port ..... Real-time output port 1
(6 bits
If real-time output is enabled when bit 7 (RTPOE01) of real-time output port control register 1 (RTPC01) is
1, the data of real-time output buffer register 1 (RTBH01, RTBL01) is transferred to the output latch in
synchronization with the generation of INTTM001. Of the transferred data, only the data of the bit specified
as the real-time output port by setting real-time output port mode register 1 (RTPM01) is output from bits TO70
to TO75. It is possible to use TO70 to TO75 as inverter timer output when inverter timer output is specified
by DCEN1.
The operation mode can be selected as 6 bits
By setting INV1, it is possible to invert the output waveform. Also, by setting PWMCL1 and PWMCH1, it is
possible to perform PWM modulation of the output pattern.
If real-time output was disabled (RTPOE01 = 0) when RTPM01n = 1 and INV1 = 0, then TO70 to TO75 output
0.
The relationship between the settings for each bit of the control register and the real-time output is shown in
Table 10-7, and an example of the operation timing is shown in Figure 10-12.
