These bits are reserved.
CRCEN—CRC enable
If this bit is set, a CRC is appended to the end of each debug command. Clearing this bit
will disable transmission of the CRC.
0 = CRC disabled
1 = CRC enabled
UARTEN—UART enable
This bit is used to enable or disable the UART. This bit is ignored when
0 = UART Disabled.
1 = UART Enabled.
ABCHAR—Auto-baud character
This bit selects the character used during auto-baud detection. This bit cannot be written
by the CPU if
0 = Auto-baud character to be measured is
1 = Auto-baud character to be measured is
ABSRCH—Auto-baud search mode
This bit enables auto-baud search mode. When this bit is set, the next character received is
measured to set the Baud Rate Reload register. This bit clears itself to zero once the reload
register has been written. This bit is automatically set when
communication error occurs. This bit cannot be written by the CPU if the
0 = Auto-baud search disabled.
1 = Auto-baud search enabled.

DBGHALT—Debug halt
Setting this bit to one causes the device to enter Debug Halt mode. When in Debug Halt
mode, the CPU stops fetching instructions. Clearing this bit causes the CPU to start
running again. This bit is automatically set to one when a breakpoint occurs if the
