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)
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
Note:
CPU_F register is only readable with explicit register address 0xF7. The
OR F, expr and AND F, expr
instructions must
be used to set and clear the CPU_F bits
