General Purpose I/O Pins

The IS2062 SoC provides 10 GPIOs and the IS2064

SoC provides 15 GPIOs, and these GPIOs can be con-

figured using the UI tool. Table 6-2 through Table 6-5

provide the GPIO configuration details of the IS2062/64

SoC.

The MFB pin must be configured as the power on/off

key and the remaining pins can be configured for any

one of the default functions as provided in Table 6-2

and Table 6-3.

Some pins can be configured to indicate or control the

external devices. The most popular applications are

NFC for easy pairing and Buzzer for indication and

external audio amplifier for loud speaker.
