Description
Unused
No System Reset will be executed
Set bit = “1” triggers a System Reset. After the
restart of the logic, the SysR will be cleared and in
bit 4 “SR” in the register Control_Status will be set
Unused
Reference
See section 4.2.1.
Bit positions labelled as “X” are not implemented and will return a “0” when read.
3.3. WATCH PAGE REGISTER FUNCTION
Watch Page registers are coded in the Binary Coded Decimal (BCD) format; BCD format is used to simplify
application use.
