Memory Type Speciers
The mikroBasic PRO for PIC32 supports usage of all memory areas.
Each variable may be explicitly assigned to a specic memory space by including a memory type specier in the
declaration, or implicitly assigned.
The following memory type speciers can be used:
- code
- data
- rx (reserved for compiler purposes only)
- sfr
code
Description The code memory type may be used for allocating constants in program memory.
Example
‘ puts txt in program memory
const txt = “Enter parameter” code
data
Description This memory specier is used when storing variable to the Data RAM.
Example
‘ puts data_buffer in data ram
dim data_buffer as char data
rx
Description This memory specier allows variable to be stored in the working registers space (WREG0-
WREG15).
Example
‘ puts y in the working registers space
dim y as char rx
sfr
Description This memory specier allows user to access special function registers. It also instructs compiler to
maintain same identier in source and assembly.
Example
dim y as char sfr ‘ puts y in SFR space
Note: If none of the memory speciers are used when declaring a variable, data specier will be set as default by the
compiler.
