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

operation or data to be inserted into the transmit 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 transmit block pointer

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