DBGMODE—DEBUG mode
The device enters DEBUG mode when this bit is 1. When in DEBUG mode, the eZ8 CPU
stops fetching new instructions. Clearing this bit causes the eZ8 CPU to restart. This bit is
automatically set when a
Flash read protect option bit is enabled, this bit can only be cleared by resetting the device.
It cannot be written to 0.

DBGACK—Debug acknowledge
This bit enables the debug acknowledge feature. If this bit is set to 1, the OCD sends a
Debug acknowledge character (
0 = Debug acknowledge is disabled
1 = Debug acknowledge is enabled
Reserved—Must be 0
RST—Reset
Setting this bit to 1 resets the Z8F04xA family device. The device goes through a normal
Power-on reset sequence with the exception that the On-Chip Debugger is not reset. This
bit is automatically cleared to 0 at the end of reset.
0 = No effect
