When an 8051 microcontroller power up, the stack pointer contained value is 07, by default, as shown in the above figure. If we perform ‘PUSH’ operation, then the stack pointer address will be increased and shifted to another register. To avoid this problem, before starting the program, w...
In the Cortex®-M processors, the Stack Pointer is register R13 in the register bank. Physically there are two stack pointers in the Cortex-M processors, but only one of them is used at a time, depending on the current value of the CONTROL register and the state of the processor (see...
On ST9 devices, the system stack may be located in the Register File or in data memory space. The ST9 stack pointer moves from the top to the bottom of the stack area. A solution to detect stack overflow is to reserve the first two bytes after the bottom of the stack...
pointer to next pbuf in a pbuf chain • payload: pointer to packet data payload • len: length of the data content of the pbuf • tot_len: sum of pbuf len plus all the len fields of the next pbufs in the chain • ref: (on 4 bits) reference count...

When it breaks at main(), set a watchpoint on the stack address that the scan found, casting it as a pointer to an int (working with watchpoints can be a bit finicky, so make sure these steps are in exactly this order, with this exact syntax): (gdb) r The program being debug...
Answer to: What do program counter, status register, and stack pointer mean? Where are they kept in the MSP430 microcontroller? By signing up,...
> Stack Pointer must always point to the same address. In other words, stack must be always the same. I don't follow the reasoning here. To use a single stack for different tasks means that for a task switch, the stack content of the previously running task has to b...
Changed the insecure decoding API decoration to 'deprecated' which is defined in src/bacnet/basic/sys/platform.h and can be disabled during a build. (#481) Changed some of the BACnet primitive value encoders so that all of them can accept a NULL APDU buffer pointer when only the length ...
