OCD Status Register
DBG
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.
1 = Reset the Flash Read Protect Option Bit device.
The OCD Status register reports status information about the current state of the debugger
and the system.
DBG—Debug Status
0 = NORMAL mode
1 = DEBUG mode
HALT—HALT Mode
0 = Not in HALT mode
1 = In HALT mode
FRPENB—Flash Read Protect Option Bit Enable
0 = FRP bit enabled, that allows disabling of many OCD commands
1 = FRP bit has no effect
Reserved—Must be 0
