DEBUG mode or if the 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 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
zero). 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 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
zero). If the device is not in DEBUG mode or if the Read Protect Option Bit is
enabled, this command returns
Write Program Memory (0AH)—The Write Program Memory command writes data
to Program Memory. This command is equivalent to the LDC and LDCI instructions.
Data can be written 1-65536 bytes at a time (65536 bytes can be written by setting size
to zero). The on-chip Flash Controller must be written to and unlocked for the
programming operation to occur. If the Flash Controller is not unlocked, the data is
discarded. If the device is not in DEBUG mode or if the Read Protect Option Bit is
enabled, the data is discarded.
