Description
Get peripheral register reg (8 bit)
Return
The value of the register
Code Example
The following code example uses the GetPerReg function.
The SMK900.evi file used for this example can be downloaded at the bottom of this page.
/* Example Code
* GetPerReg/SetPerReg
*
* get reg, val
* get valInit
*
* return valInit and
* if useParams
* new reg of Periph
* else
* 0x01 (new reg == val) or 0x00 (new reg != val)
* on 16 bits
*
* example VMExecuteCmd:
* cmd: |reg |val
* 0xfb 0x0e 0x00 0x0c 0x00 0x0e [0x?? 0x?? 0x?? = macAdress] 0x00 0x00 0x01
* rsp: 0xfb 0x0a 0x00 0x2d 0x00 0xe1 0x1e 0x01
