Description: These files allow asserting system power cycling, switching |
|
power supply units on and off and system's main power domain |
|
shutdown. |
|
Expected behavior: |
|
When pwr_cycle is written 1: auxiliary power domain will go |
|
down and after short period (about 1 second) up. |
|
When psu1_on or psu2_on is written 1, related unit will be |
|
disconnected from the power source, when written 0 - connected. |
|
If both are written 1 - power supplies main power domain will |
|
go down. |
|
When pwr_down is written 1, system's main power domain will go |
|
down. |
|
|
|
The files are write only. |
