OCD Status Register
IDLE
0 = OCDCNTR is setup as counter
1 = OCDCNTR generates hardware break when PC == OCDCNTR
BRKZRO—Break when OCDCNTR ==
If this bit is set, then the OCD automatically sets the DBGMODE bit when the
OCDCNTR register counts down to
is not reset when the part leaves DEBUG Mode.
0 = OCD does not generate BRK when OCDCNTR decrements to
1 = OCD sets DBGMODE to 1 when OCDCNTR decrements to
Reserved—Must be 0
RST—Reset
Setting this bit to 1 resets the device. The controller goes through a normal POR
sequence with the exception that the On-Chip Debugger is not reset. This bit is
automatically cleared to 0 when the reset finishes.
0 = No effect.
1 = Reset the device.
The OCD Status register
the debugger and the system.
IDLE—CPU idle
This bit is set if the part is in Debug mode (DBGMODE is 1) or if a BRK instruction has
occurred since the last time OCDCTL was written. This can be used to determine if the
CPU is running or if it is idle.
0 = The eZ8 CPU is running.
1 = The eZ8 CPU is either stopped or looping on a BRK instruction.
HALT—HALT Mode
0 = The device is not in HALT mode.
1 = The device is in HALT mode.
RPEN—Read Protect Option Bit Enabled
0 = The Read Protect Option Bit is disabled (Flash option bit is 1).
1 = The Read Protect Option Bit is enabled (Flash option bit is 0), disabling
Reserved—Must be 0
