PIN DESCRIPTIONS AND CONFIGURATION

The pinouts for the package, along with system-level application diagrams, are detailed in the following section:

• 32-Pin SQFN (32-SQFN)

Note:

For a summary of the available pin combinations and their corresponding target applications, refer to

Table 1-1.

Pin descriptions are detailed in Section 2.2, "Pin Descriptions," on page 14. For details on the CFG_SEL0 and CFG_-

SEL1 Configuration Select signals, refer to Section 3.3, "Configuration Selection (CFG_SEL0/CFG_SEL1)," on

page 24.

Note:

When an “_N” is used at the end of the signal name, it indicates that the signal is active low. For example,

RESET_N indicates that the reset signal is active low.
