EXR is an 8-bit register that contains the trace bit (T) and three interrupt mask bits (I2 to I0).
Operations can be performed on the EXR bits by the LDC, STC, ANDC, ORC, and XORC
instructions.
For details, see section 5, Exception Handling.

Description
Zero Flag
Set to 1 to indicate zero data, and cleared to 0 to
indicate non-zero data.
Overflow Flag
Set to 1 when an arithmetic overflow occurs, and
cleared to 0 otherwise.
Carry Flag
Set to 1 when a carry occurs, and cleared to 0
otherwise. A carry has the following types:
The carry flag is also used as a bit accumulator by bit
manipulation instructions.
Description
Trace Bit
When this bit is set to 1, a trace exception is generated
each time an instruction is executed. When this bit is
cleared to 0, instructions are executed in sequence.
Reserved
These bits are always read as 1.
Interrupt Mask Bits
These bits designate the interrupt mask level (0 to 7).
Carry from the result of addition
Borrow from the result of subtraction
Carry from the result of shift or rotation
