FIGURE 11 PMC BISERIAL-II STATUS 1 BIT MAP
The Switch Read Port has the user bits. The user bits are connected to the eight
dip-switch positions. The switches allow custom configurations to be defined by
the user and for the software to identify a particular board by its switch settings
and to configure it accordingly.
The Dip-switch is marked on the silk-screen with the positions of the digits and the
'1' and '0' definitions. The numbers are hex coded. The
example shown would produce 0x12 when read [and shifted
down] from the BIS2_STAT1 port.
Tx_fifo_mt3-0 is '1' when the Transmit FIFO is empty for that channel. When data
