GETREG

GETREG

Top  Previous  Next

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.

 

noticeIn 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.
