How to modify the LISTSTAR register in the S32K312 BCTU module？

Hello Everyone,

LISTSART is a read-only register. In the S32K3XXRM, these two locations describe the functionality of LISTSART.

1) Is the value of the LISTSART register unmodifiable?

2) Is the reset value of LISTSART[LISTZE] equal to the maximum number of channels in CL?

3) If LISTSTAR[LISTSZ] cannot be modified, what are the use cases for this register?

Thanks.

Hi,

1) yes, it is read only
2) it indicates the size of the CL in number of elements. 32 is implemented
3) module use it to indicate last list element. It wraps the pointer to list address 0 when the CL pointer reaches the last available list address/element (LISTSTAR[LISTSZ] minus 1)
