3.2.4 Threshold High RAM
Address: ME 0x020080
The Threshold High RAM is a memory area of 64 12-bit locations, mapped within the
IP memory space. It is used for specifying a threshold high value used by the system
to take specific actions, in relation with the Channel List. The position 0 of this table
gives the value for the channel #0, and so on, until the position 47 corresponding to
channel #47. The locations 48 to 63 are not used.
3.2.5 Threshold Low RAM
Address: ME 0x020100
The Threshold Low RAM is a memory area of 64 12-bit locations, mapped within the
IP memory space. It is used for specifying a threshold high value used by the system
to take specific actions, in relation with the Channel List. The position 0 of this table
gives the value for the channel #0, and so on, until the position 47 corresponding to
channel #47. The locations 48 to 63 are not used.
