Question:How to change the timing of the communication path selection pulse output on the FR830

By changing the value at address 145 in Parameter Table 2, it is possible to adjust the timing at which the communication path selection pulse is output after the reset is released.

When the rising waveform of the reset signal is large due to a capacitor in the reset line on the target board, the time from the cancellation of the reset of the microcomputer to the input of the communication path selection pulse becomes too short and the programmer. Communication with may not be possible normally. In such a case, adjust the timing from the reset release with the writer to the communication path selection pulse output.



Address #145: Value 00~FF (Wait time 0ms~255ms)


*When you access the Parameter Table 2 screen, you will be asked to enter the password. Enter "AF200".




*When you change the setting value on the Parameter Table 2 screen, click the [OK] button on the right end of the screen to reflect the setting value on the programmer.
