Hardware Description
RL2/RDIN/RCLKI
RL1/RDIP/ROID
Ternary coded signals received at multifunction ports RL1 and RL2 from a ternary
interface. The ternary interface is selected if LIM1.DRS is reset.
Digital dual-rail signals received on ports RDIP and RDIN. The dual-rail interface is
selected if LIM1.DRS and FMR0.RC1 is set.
Unipolar data on port ROID received from a fiber-optical interface. The optical
interface is selected if LIM1.DRS is set and FMR0.RC1 is reset.
