Receive Termination Control (RxTSEL):
Upon power up, the receivers are in "High" impedance. Switching
to internal termination can be selected through the microprocessor
interface by programming the appropriate channel register. How-
ever, to switch control to the hardware pin, RxTCNTL must be pro-
grammed to "1" in the appropriate global register (0x0FE2). Once
control has been granted to the hardware pin, it must be pulled
"High" to switch to internal termination.
