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 DEBUG 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

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 discarded. If the Flash
Read Protect Option bit is enabled, only writes to the Flash Control Registers are allowed
and all other register write data values are discarded.

Read Register (09H)—The Read Register command reads data from the Register File.
Data can be read 1–256 bytes at a time (256 bytes can be read by setting size to 0). If the
device is not in DEBUG mode or if the Flash Read Protect Option bit is enabled, this com-
mand returns

Write Program Memory (0AH)—The Write Program Memory command writes data
to Program Memory. This command is equivalent to the

The on-chip Flash Controller must be written to and unlocked for the programming oper-
ation to occur. If the Flash Controller is not unlocked, the data is discarded. If the device
