BIS3_IO_DATA

[$10] BiSerial III Parallel Data Output Register read/write
DATA BIT
31-0
FIGURE 11
There are 32 potential output bits in the parallel port. The Direction, Termination, and
Mux Control registers are also involved. When the direction is set to output, and the
Mux control set to parallel port the bit definitions from this register are driven onto the
corresponding parallel port lines.
This port is direct read-write of the register. The I/O side is read-back from the
BIS3_IO_RDBK port. It is possible that the output data does not match the I/O data in
the case of the Direction bits being set to input or the Mux control set to state-machine.

BIS3_IO_DIR

[$14] BiSerial III Direction Port read/write
DATA BIT
31-0
FIGURE 12
When set ('1') the corresponding bit in the parallel port is a transmitter. When cleared
('0') the corresponding bit is a receiver. The corresponding Mux control bits must also
be configured for parallel port.
