4.3 PIN USAGE INFORMATION
This section contains tables summarizing various aspects of the pin usage for the TMPR3922AU.
TABLE 4.3a lists the standard versus multi-function usage for each TMPR3922AU pin, if applicable.
Those signal names shown in parentheses are test signals for debugging purposes only. The column
showing the multi-function select signal and reset state indicates the internal control signal used to
select the multi-function mode, as well as the default configuration of each multi-function pin during
reset. The "Bus Arb State" column shows which pins are tri-stated whenever the DGRNT* signal is
asserted in response to a DREQ*(external bus arbitration request).
