Signals/Connections
1.6 GPIO, TDM, UART, and Timer Signals
The general-purpose input/output (GPIO), time-division multiplexed (TDM), universal asynchronous
receiver/transmitter (UART), and timer signals are grouped together because they use a common set of signal lines.
Individual assignment of a signal to a specific signal line is configured through internal registers.
Table 1-7
describes the signals in this group.
