memory question

Dear Expert:

is there a bit-band region of SRAM in KE02(not AIPS)? below is from the KE02 reference manual:

in ke06 refence manual,it is clear description about the SRAM bit_band:

thanks for your great support.

The KE series does not implement bit-banding (the description is probably a generic one that is used in all documents).

However it does include a bit-manipulation engine which does more or less the same thing as bit-banding (even with more flexibility, although using different address calculations). Unfortunately it can only access peripherals on the KE parts and not SRAM....

Hi,

Actually all KE families employ Bit Manipulation Engine (BME) techniques to support bit banding.

Dear Expert:

thanks for your support.

But you can download the AN4838.pdf from www.nxp.com

The is a description below:

KE04 and KE06 are indeed exceptions in that there is really a bit-banding capability in the upper SRAM (I didn't think that any Kinetis Cortex-m0+ parts had it), however it is IS NOT implemented in the KE02.
