Select Corner Frequency of DCO-R
Setting this bit reduces the corner frequency of the DCO-R circuit by the
factor of ten to 0.2 Hz. See
Note: Reducing the corner frequency of the DCO-R circuitry increases the

Multi Purpose Analog Switch
Controls the multi purpose analog switch at receive line interface if
GPC(3:6).ENMPAS are all set to ´1´ . If RLT is not configured at any multi
function port, only MPAS controls the switch. If RLT is configured at one
of the multi function ports see
