This register contains data read from the block pointer RAM after an indirect block read operation

or data to be inserted into the block pointer RAM in an indirect block write operation.

Note

This register is not byte addressable. Writing to this register modifies all the bits in the register.

Byte selection using byte enable signals (CBEB[3:0]) are not implemented. However, when all

four byte enables are negated, no access is made to this register.

BPTR[8:0]:

The indirect block pointer (BPTR[8:0]) configures the block pointer of the block specified by

the Indirect Block Select register. The block pointer to be written to the block pointer RAM, in

an indirect write operation, must be set up in this register before triggering the write. The

block pointer value is the block number of the next block in the linked list. A circular list of
