May 24, 2019 00:00

Hi,

I have been trying to resolve this issue for several days and I can't find the root cause.

The Main program uses def21489.h

Include file def21489.h has BIT_11 defined correctly

App.ldf defines correct Architecture

Why does CLKPL display as 0x00000800?

The CLKPL register value and the macro definition are not the same.

Thanks

Dan

Hi Dan,

Can you please let me know which CCES version are you working with? Please refer the below image. We can see the correct one.

Please refer the file from Installation Path:\Analog Devices\CrossCore Embedded Studio 2.8.3\SHARC\include\def21489.h

Regards,
Lalitha.S

Hi Lalitha.S,

I am using CCES version 2.8.3.0. Why doesn't the Macro Expansion display the correct value as well?

Thanks

Dan

The register browser displays the value of the CLKPL bitfield of register SPICTL.
The CLKPL macro defined in def21489.h is a bit mask that can be used to manipulate accesses of SPICTL - it is not the value held in that bitfield.
If you want to access the value of a bitfield you might do an access of the register using these macros, for example *pSPICTL&CLKPL.
