[Register][Chip][Date Sheet] How to write register number into system according data sheet



Data Sheet will write like the below.

Tell which bit represent what function.



0 bit - 14 bit  represent Rate limit for priority (R/W  can read and write)



15 bit (R/O only can read )





system("echo 0x69c 0x0014015f > /proc/avalanche/switch_write_reg");



0x69c mean which register



0x0014015f  can write down like second row

According to second row can write to third row.




If I want which function work, just change which bit status.

And third row convert to second row.




Then write second row number to 0x69c.

The description like





system("echo 0x69c 0x0014015f > /proc/avalanche/switch_write_reg");
