Polling GPIO Bridging data are sampled every Sub-Link polling, whose basic interval is controlled by register
R_SLINK_POL_TIM_UP/_DN. Remote 2-wire access may become long transaction and could lengthen
Through GPIO polling reflection interval.

Remote UART bridge is supported with Sub-Link Polling GPIO input/output. Remote UART Tx and Rx bridge
baud rate is supposed to be designed against Sub-Link Polling interval to accommodate deterministic jitter
caused by intermittent Sub-Link communication timing.
