Read OCD Control Register (
reads the value of the OCDCTL register. 
Write Program Counter (
data that follows to the eZ8 CPU’s Program Counter (PC). If the device is not in DEBUG
mode or if the Read Protect Option bit is enabled, the Program Counter (PC) values are
discarded.
Read Program Counter (

Read Protect Option Bit is enabled, this command returns
Write Register (
Data can be written 1–256 bytes at a time (256 bytes can be written by setting size to 0). 
If the device is not in DEBUG mode, the address and data values are discarded. If the Read
Protect Option Bit is enabled, then only writes to the on-chip peripheral registers are al-
lowed and all other register write data values are discarded.
