16.10.5 Commands to Reset CPU
rstc (cold reset CPU)
This command cold-resets the CPU.
When the CPU is reset, the internal circuits are initialized as follows:
The memory contents and the debugging status such as break and trace conditions are not modified.
Refer to the "Technical manual" of each model for the bus and I/O initial statuses when using in a mode other
than simulator mode.
The function of the rstc command changes according to the debugger mode.
ICE mode
The process above is executed and the S1C33 chip is also reset. The target board is not reset.
ICD mode
The process above is executed and the S1C33 chip is also reset. The target board is not reset.
Furthermore, when the target system is in a free-run state, the rstc command suspends the program execution
forcibly before resetting. The target system connected to the S5U1C33000H enters a free-run state when the
target board is reset. The rstc command can be used to suspend the program execution in this case.
Debug monitor mode
The rstc command functions the same as the rsth command. It does not reset the S1C33 chip and does not
initialize the TTBR register.
Simulator mode
The boot address is determined by the MCU/MPU specification in the parameter file.
