(1) This mode is only supported if there is at least a one bit delay between
characters received by the SDM-SIO1A
This will place the SDM-SIO1A unit into shutdown mode where only SDM
communications will operate. This means any data coming into the SDM-SIO1A
on the RS-232/RS-485 interface will be lost.
This is the lowest possible power mode and for optimum power efficiency the
SDM-SIO1A should be placed in this mode whenever possible.
