ERROR IN PROGRAMMING MANUAL?????????

[debruyne.marc]

hello sir

can someone, help me with that "SUB SP,#$9 " ,with is mentioned in the LATEST PROGRAMMING MANUAL OF STM8S PAGE 151.

if you write that in an even very 1line program, you have an error

Can't match Addressing mode ' SUB SP,#$9'

is there a n error of me, or is the manual example not correct

thanks for the help

The manual looks okay to me.

I guess you are using an assembler that uses a different syntax for hex immediates.

You should tell us which assembler you use. E.g. in sdasstm8 (the assembler that comes with SDCC), the syntax would be sub sp, #0x09.

Unfortunately ST's participation on the STM8 forum is rather lackluster
