CHAPTER 16: DEBUGGER
Resetting the CPU
Note: The function of the rstc command changes according to the debugger mode.
306
(1) Internal registers of the CPU
(2) The execution counter is reset to 0.
(3) The [Source] and [Register] windows are redisplayed.
* The boot address is the 4-byte value stored from the beginning of the vector table that is specified by the
The CPU is cold-reset when the rstc command ([Reset Cold] command on the [Run] menu, or the [Reset
cold] button) is executed, or is hot-reset when the rsth command (or [Reset Hot] command on the [Run]
menu, or the [Reset hot] button) is executed.
When the CPU is reset, the internal circuits are initialized as follows:
R0–R15:
PC:
SP:
PSR:
AHR, ALR: 0xaaaaaaaa
Because the PC is set to the boot address, the [Source] window is redisplayed beginning with that address.
The [Register] window is redisplayed with the internal registers initialized as described above.
The memory contents are not modified.
TTBR register. At cold-reset, the TTBR register is initialized to 0x80000 or 0xc00000. At hot-reset, the
TTBR register retains the set value.
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.
