Inituser - Fujitsu F2MC-16L Series User Manual

REGISTER [ R
3.5.11.
Show Registers, Change Register Contents
The register command, without parameters displays the CPU register contents (AH, AL, SP,
IP, FP, the current register bank RW0..7, ILM, RP, CCR, ADB, DTB, DPR, USB, USP, SSB,
SSP, PCB, PC):
AH AL SP
0000 0000 000000 000000 000000
ILM RP CCR
0 00 -S-----
If ANSI has been enabled (EMULATION ON) all registers that have been changed are
different coloured with different background to easily identify the changes.
If RegisterName and Value are specified, the register will be updated.
If the value is not specified, the monitor will enter an 'edit register mode'. It will print the
current value and prompt for a new value. The user can either specify a new value or simply
press RETURN to keep the actual value. Then the next CPU register and its content is
displayed and can be changed. To exit this edit mode, press the ESC key or type /↵. This mode
is available only for pure CPU register, but not for combined (e.g. IP).
>r al f000↵
>r rw0↵
>r ip ff0553↵
>r t 0↵
NOTE: Some "registers" are no actual register. SPP (stack pointer offset, SSP or USP),
SPB(stack pointer bank, SSB or USB), SP (stack pointer, SSB:SSP or USB:USP), IP
(instruction pointer, PCB:PC) and FP(frame pointer, SSB:RW3 or USB:RW3) are
composed of a bank register and a belonging pointer. Others are part of the processor
state PS (ILM, RP, CCR, flags I, S, Z, C, T, V, N of CCR).
3.5.12.

INITUSER

Pre-define system stack and instruction pointer
Initialises stack (SSB, SSP, RW3) and/or instruction pointer (PCB:PC) in order to use a stack
area within the monitor data RAM and to set the instruction pointer to the address pointed to
by the current reset vector.
>inituser↵
Use this command to initialise and test your application software after a program download,
when the stack is not set yet. See NOTE of Trace command.
The two operations of this command must be confirmed with 'Y' or ENTER or cancelled by
any other key.
