11.2.13
The Cycle Trace Control Register (CTCON), used only during application development is an
8-bit read/write register that adjusts CPU operation to emulate the in-circuit emulator's bus
trace mode. Setting the CT bit to "1" suspends CPU processing while the internal core bus
provides address and data outputs to external circuits.
After a system reset, this register contains 0x00.
Bit Descriptions
CT
This bit controls cycle trace operation. Setting it to "1" adjusts CPU operation to emulate the
in-circuit emulator's bus trace mode. Resetting it to "0" disables cycle trace operation.

A "0” indicates a reserved bit. Always write "0” to it.
Writing "1” produces unreliable operation.
