Mode Select Input.
This pin is used to select the operating mode of the
LXT384. In Hardware Mode, the parallel processor interface is disabled
and hardwired pins are used to control configuration and report status.
In Parallel Host Mode, the parallel port interface pins are used to control
configuration and report status.
In Serial Host mode, the serial interface pins: SDI, SDO, SCLK and
CS
are used.
For Serial Host Mode, the pin should connected to a resistive divider
consisting of two 10 k
resistors across V
CC
and Ground.
