FIFO High Data Bits — The FIFO High data bits provide access to bits [15:8] of data in the FIFO. This register
is not used in event only modes and will read a $00 for valid FIFO words.
Bit 7
FIFO Low Data Bits — The FIFO Low data bits contain the least significant byte of data in the FIFO. When
reading FIFO words, read DBGFX and DBGFH before reading DBGFL because reading DBGFL causes the
FIFO pointers to advance to the next FIFO location. In event-only modes, there is no useful information in DBGFX
and DBGFH so it is not necessary to read them before reading DBGFL.
