The "
TCK Divider Setting (0-30x)" allows you to slow down the TCK clock, thereby reducing the Programming speed.
This is done by extending the low period of the clock.
Refer the following table for specific frequency settings for the HW-USBN-2B programming cable:
| Divider | Programming Frequency (TCK) |
0 | 30.00 MHz (Default) |
| 1 | 15.00 MHz |
| 2 | 10.00 MHz |
| 3 | 7.50 MHz |
| 4 | 6.00 MHz |
| 5 | 5.00 MHz |
| 6 | 4.29 MHz |
| 7 | 3.75 MHz |
| 8 | 3.34 MHz |
| 9 | 3.00 MHz |
