USER’S MANUAL

RESET:
The status register (SR) contains condition codes, an interrupt priority mask, and three
control bits. The condition codes are contained in the condition code register (CCR),
the lower byte of the SR. (The lower and upper bytes of the status register are also
referred to as the user and system bytes, respectively.) In user mode, only the CCR is
available. In supervisor mode, software can access the full status register.
This field places the processor in one of two tracing modes or disables tracing. Refer
to Table D-2.
