Read Memory, Write Register, Read Register, Read Memory CRC, Step Instruction, Stuff
Instruction and Execute Instruction commands.
DBG ← 03H
DBG → RuntimeCounter[15:8]
DBG → RuntimeCounter[7:0]
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 (OCDCTL[7]) can only be set to 1, it cannot be cleared to 0
and the only method of returning the device to normal operating mode is to reset the
device.
DBG ← 04H
DBG ← OCDCTL[7:0]
Read OCD Control Register (05H). The Read OCD Control Register command reads the
value of the OCDCTL Register.
DBG ← 05H
DBG → OCDCTL[7:0]
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.
DBG ← 06H
DBG ← ProgramCounter[15:8]
DBG ← ProgramCounter[7:0]
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 FFFFH.
DBG ← 07H
DBG → ProgramCounter[15:8]
DBG → ProgramCounter[7:0]
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.
DBG ← 08H
DBG ← {4’h0,Register Address[11:8]}
DBG ← Register Address[7:0]
DBG ← Size[7:0]
DBG ← 1-256 data bytes
