Chapter 2 Pin Descriptions

2.3

Pin Mode

This section contains tables summarizing various aspects of the pin usage for the TMPR3911/12. Table

2.3.1 lists the standard versus multi-function usage for each TMPR3911/12 pin, if applicable. The column

showing the multi-function select indicates the corresponding bit in the MIOSEL register, 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).
