Description
Perform flash chip erase (mass erase) and clear lock bits. If any other
command, except READ_STATUS, is issued, then the use of
CHIP_ERASE is disabled.
Write configuration data. Refer to Table 36 for details
Read configuration data. Returns value set by WR_CONFIG command.
Return value of 16-bit program counter. Returns 2 bytes regardless of
value of bit 2 in instruction code
Read status byte. Refer to Table 37
Set hardware breakpoint
Halt CPU operation
Resume CPU operation. The CPU must be in halted state for this
command to be run.
Run debug instruction. The supplied instruction will be executed by the
CPU without incrementing the program counter. The CPU must be in
halted state for this command to be run. Note that yy is number of bytes
following the command byte, i.e. how many bytes the CPU instruction has
(see Table 28)
Step CPU instruction. The CPU will execute the next instruction from
program memory and increment the program counter after execution.
The CPU must be in halted state for this command to be run.
Step and replace CPU instruction. The supplied instruction will be
executed by the CPU instead of the next instruction in program memory.
The program counter will be incremented after execution. The CPU must
be in halted state for this command to be run. Note that yy is number of
bytes following the command byte, i.e. how many bytes the CPU
instruction has (see Table 28)
Return value of 16-bit chip ID and version number. Returns 2 bytes
regardless of value of bit 2 of instruction code
