On-Chip Debugger Commands
As this register is overwritten by various OCD commands, it must only be used to 
generate temporary break points, such as stepping over CALL instructions or running to a
specific instruction and stopping.
When the OCDCNTR register is read, it returns the inverse of the data in this register. The
OCDCNTR register is only decremented when counting. The mode where it counts the
number of clock cycles in between execution is achieved by counting down from its
maximum count. When the OCDCNTR register is read, the counter appears to be counted
up as its value is inverted. The value in this register is always inverted when it is read. If this
register is used as a hardware break point, the value read from this register will be inverse of
the data actually in the register.
The host communicates to the OCD by sending OCD commands using the DBG interface.
During normal operation, only a subset of the OCD commands are available. In Debug
mode, all OCD commands are available unless the user code is protected by programming
the Read Protect option bit (RP). The Read Protect option bit prevents the code in memory
from being read out of the Z8FMC16100 Series Flash MCU device. When this option is
enabled, several OCD commands are disabled.
