Bit 5 : Reserved
Bit 4 : XIO Set by the user to select between the register banks
0 = Bank 0
1 = Bank 1
Bit 3 : Super Indicates whether the CPU is executing user code or Supervisor Code. (This code cannot be accessed
directly by the user and is not displayed in the ICE debugger.)
0 = User Code
1 = Supervisor Code
Bit 2 : Carry Set by CPU to indicate whether there has been a carry in the previous logical/arithmetic operation
0 = No Carry
1 = Carry
Bit 1 : Zero Set by CPU to indicate whether there has been a zero result in the previous logical/arithmetic operation
0 = Not Equal to Zero
1 = Equal to Zero
Bit 0 : Global IE Determines whether all interrupts are enabled or disabled
0 = Disabled
1 = Enabled
Bit [7:0] : Data [7:0] 8-bit data value holds the result of any logical/arithmetic instruction that uses a source address-
