GETREG
Contents |
Action
Reads a byte from an internal register.
Syntax
var = GETREG( Reg )
Remarks
Most AVR chips have 32 registers named R0-R31. The GetReg function will return the value of the specified register.
|
Reg |
The register name : R0-R31 or a register definition. |
|
Var |
The name of a variable that will be assigned with the content of the register. |
PEEK and POKE work with an address. And will return a HW register on the Xmega since Xmega has a different address map.
GetReg and SetReg will read/write registers on all AVR processors.
In version 2078, all internal registers (R0-R31) are made available as normal BYTE variables. This means that you can simply assign or read a register from basic : Rx=value.
This is more convenient than using SETREG and GETREG.
