Hi guys,

---------

From IDLE_PRI to START_DETECT_PRI (145.2.5.7, Page 141 line 10)

Comment

The condition:           !pwr_app_pri * pwr_app_sec           doesn’t make sense that only if the secondary is powered we can  go to START_DET_PRI.

 

pwr_app_pri	pwr_app_sec	START_DET_PRI
0	0	0
0	1	1
1	0	0
1	1	0

The conditions should allow to move to START_DET_PRI in the following conditions:

1. !pwr_app_pri OR
2. !pwr_app_sec

i.e. the condition should be: !pwr_app_pri + !pwr_app_sec          

pwr_app_pri	pwr_app_sec	START_DET_PRI
0	0	1
0	1	1
1	0	1
1	1	0

Proposed remedy:

!pwr_app_pri * pwr_app_sec          

To: !pwr_app_pri + !pwr_app_sec
