Write OCD Control Register (04H)—The Write OCD Control Register command
writes the data that follows to the OCDCTL register. When the Flash Read Protect
Option Bit is enabled, the DBGMODE bit (
be cleared to 0 and the only method of returning the device to normal operating mode
is to reset the device.

Read OCD Control Register (05H)—The Read OCD Control Register command
reads the value of the OCDCTL register.

Write Program Counter (06H)—The Write Program Counter command writes the
data that follows to the eZ8 CPU’s Program Counter (PC). If the device is not in DE-
BUG mode or if the Flash Read Protect Option bit is enabled, the Program Counter
(PC) values are discarded.

Read Program Counter (07H)—The Read Program Counter command reads the
value in the eZ8 CPU’s Program Counter (PC). If the device is not in DEBUG mode
or if the Flash Read Protect Option bit is enabled, this command returns

DBG
DBG
Write Register (08H)—The Write Register command writes data to the Register
File. 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 dis-
carded. If the Flash Read Protect Option bit is enabled, only writes to the Flash Con-
trol Registers are allowed and all other register write data values are discarded.
