GPIO FUNCTIONS

ALARM

ALARM pin is asserted when an internal unmasked alarm is detected. Alarm mask is set by

ALM_MASK register.

FRCLK

Fast reconfiguration interface clock.

FRCS

Fast reconfiguration interface chip select. Internal pullup.

FRDI0

Fast reconfiguration interface data bit 0.

FRDI1

Fast reconfiguration interface data bit 1.

FRDI2

Fast reconfiguration interface data bit 2.

FRDI3

Fast reconfiguration interface data bit 3.

RESET

Device reset input, active low. Must be toggled after power up. Internal pullup.

SCANEN

TI use only, can be left unconnected. Internal pulldown.

SCLK

Serial programming interface (SPI) clock input.

SCS

Serial programming interface (SPI) device select input, active low. Internal pullup.

SDI

Serial programming interface (SPI) data input.

SDO

Serial programming interface (SPI) data output. High impedance when not reading out SPI

data.
