Note 3:

Configuration strap values are latched on Power-On Reset (POR) and the rising edge of RESET_N (external

chip reset). Configuration straps are identified by an underlined symbol name. Signals that function as con-

figurations traps must be augmented with an external resistor when connected to a load. Refer to Section

3.4, "Configuration Straps and Programmable Functions" for additional information.

Note 4:

The PROG_FUNC2 buffer type is I/O6. The PROG_FUNC7 buffer type is I/O10. All other PROG_FUNCx

pins have a buffer type of I/O12.

Note 5:

Configuration strap values are latched on Power-On Reset (POR) and the rising edge of RESET_N (external

chip reset). Configuration straps are identified by an underlined symbol name. Signals that function as con-

figurations traps must be augmented with an external resistor when connected to a load. Refer to Section

3.4, "Configuration Straps and Programmable Functions" for additional information.

SPI_DI

SPI data input, when configured for SPI operation.

GPIO9

I/O12

General purpose input/output 9.

CFG_BC_EN

Battery Charging Configuration Strap.

This configuration strap is used to enable battery charging. Refer to

Section 3.4.4, "Battery Charging Configuration (CFG_BC_EN)" for
