On-Chip Debugger Commands
PS025011-1010
Caution:
be generated when the program counter matches the value in the OCDCNTR register
before executing the instruction at the location of the program counter.
Because this register is overwritten by various OCD commands, it must only be used to
generate temporary breakpoints, such as stepping over CALL instructions or running to a
specific instruction and stopping.
When the OCDCNTR register is read, it returns the inverse of the data in this register. The
OCDCNTR register is only decremented when counting. The mode where it counts the
number of clock cycles in between execution is achieved by counting down from its max-
imum count. When the OCDCNTR register is read, the counter appears to have counted
up because its value is inverted. The value in this register is always inverted when it is
read. If this register is used as a hardware breakpoint, the value read from this register will
be the inverse of the data actually in the register.
The host communicates to the On-Chip Debugger by sending OCD commands using the
DBG interface. During normal operation, only a subset of the OCD commands are
available. In Debug mode, all OCD commands become available unless the user
code is protected by programming the Flash Read Protect Option Bit (FRP). The Flash
Read Protect Option Bit prevents the code in memory from being read out of the Z8
Encore! XP F1680 Series device. When this option is enabled, several of the OCD
commands are disabled. When the Read Protect Option Bit is enabled and the Information
Area Write Protect bits are enabled, asserting the TESTMODE pad does NOT put the
Table 163
command is described in further detail in the bulleted list following the table.
The table indicates those commands that operate when the device is not in DEBUG mode
Z8 Encore! XP F1680 Series in Flash Test mode.
The OCDCNTR register is used by many of the OCD commands. It counts the
number of bytes for the register and memory read/write commands. It retains
the residual value when generating the CRC. If the OCDCNTR is used to gen-
erate a BRK, its value must be written as a final step before leaving DEBUG
mode.
