BYTESWAP
DI
Parallel Mode Selection (8-/16-bit). When LOW, the LSB is output on D[7:0] and the MSB is output on
D[15:8]. When HIGH, the LSB is output on D[15:8] and the MSB is output on D[7:0].
5
OB/2C
DI
Straight Binary/Binary Twos Complement. When OB/2C is HIGH, the digital output is straight binary;
when LOW, the MSB is inverted, resulting in a twos complement output from its internal shift
register.
8
SER/PAR
DI
Serial/Parallel Selection Input. When LOW, the parallel port is selected; when HIGH, the serial
interface mode is selected and some bits of the DATA bus are used as a serial port.
9, 10
D[0:1]
DO
Bit 0 and Bit 1 of the Parallel Port Data Output Bus. When SER/PAR is HIGH, these outputs are in high
impedance.
11, 12
D[2:3]or
DIVSCLK[0:1]
DI/O
When SER/PAR is LOW, these outputs are used as Bit 2 and Bit 3 of the parallel port data output bus.
When SER/PAR is HIGH, EXT/INT is LOW, and RDC/SDIN is LOW (serial master read after convert),
these inputs, part of the serial port, are used to slow down, if desired, the internal serial clock that
clocks the data output. In other serial modes, these pins are not used.
13
D4 or
EXT/INT
DI/O
When SER/PAR is LOW, this output is used as Bit 4 of the parallel port data output bus.
When SER/PAR is HIGH, this input, part of the serial port, is used as a digital select input for choosing
the internal data clock or an external data clock. With EXT/INT tied LOW, the internal clock is selected
on the SCLK output. With EXT/INT set to a logic HIGH, output data is synchronized to an external
clock signal connected to the SCLK input.
14
D5 or
INVSYNC
DI/O
When SER/PAR is LOW, this output is used as Bit 5 of the parallel port data output bus.
When SER/PAR is HIGH, this input, part of the serial port, is used to select the active state of the SYNC
signal. It is active in both master and slave modes. When LOW, SYNC is active HIGH. When HIGH,
SYNC is active LOW.
15
D6 or
INVSCLK
DI/O
When SER/PAR is LOW, this output is used as Bit 6 of the parallel port data output bus.
When SER/PAR is HIGH, this input, part of the serial port, is used to invert the SCLK signal. It is active
in both master and slave modes.
