R0,R1,R2...................R20 global variables

#1 Post by gotronics » 02 Dec 2016 23:02

HI Mikroelektronika team

R0............R20
are these varables used by the compiler for maths data etc, such that can save them as part of the context data in RTOS. I can not find information regarding them in mikroc Pro help .

Hi,

R0,R1,R2...R20 are working registers used only by the compiler to store intermediate values during code execution, and as such shouldn't be modified by the users.

Regards,

Danilo
