The host communicates to the On-Chip Debugger by sending OCD commands using the
DBG interface. During normal operation, only a subset of the OCD commands are avail-
able. In DEBUG mode, all OCD commands become available unless the user code and
control registers are 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 Z8
