= <span class="f_Header">Remarks</span> =

When you are writing your own ASM routines and mix them with BASIC you are unable to tell which registers are used by BASCOM because it depends on the used statements and interrupt routines that can run on the background.

<span style="font-family: Arial;"> </span>

That is why Pushall saves all used registers. Use POPALL to restore the registers.

<span style="font-family: Arial;"> </span>

The saved registers are : R0-R5, R7,R10,R11 and R16-R31

 

The SREG register is also saved. The SREG register contains the processor flags and it is important to save these.

If the micro has a RAMPZ register, the RAMPZ register is saved too. RAMPZ is used to address multiple pages in flash and SRAM memory.
