Bank 17 TX Frame Data Pointer Register (0x04): TXFDPR
The value of this register determines the address to be accessed within the TXQ frame buffer. When the AUTO increment
is set, It will automatically increment the pointer value on Write accesses to the data register.
The counter is incremented by one for every byte access, by two for every word access, and by four for every double
word access.

TXFPAI TX Frame Data Pointer Auto Increment
When this bit is set, the TX Frame data pointer register increments automatically on accesses
to the data register. The increment is by one for every byte access, by two for every word
access, and by four for every doubleword access.
When this bit is reset, the TX frame data pointer is manually controlled by user to access the
TX frame location.

TXFP TX Frame Pointer
TX Frame Pointer index to the Frame Data register for access.
This field reset to next available TX frame location when the TX Frame Data has been
enqueued through the TXQ command register.
Bank 17 RX Frame Data Pointer Register (0x06): RXFDPR
The value of this register determines the address to be accessed within the RXQ frame buffer. When the Auto Increment
is set, it will automatically increment the RXQ Pointer on read accesses to the data register.
The counter is incremented is by one for every byte access, by two for every word access, and by four for every double
word access.
