GENERAL-PURPOSE PINS
Table 25 shows the functions available on each of the general-
purpose pins on the LFCSP and WLCSP options of the AD4697/
AD4698, plus the relative priority of those functions (lower numbers
indicate higher priority). To configure the general-purpose pins for
a given function, all higher priority functions must be disabled. The
Busy Indicator section, Threshold Detection and Alert Indicators
section, Serial Data Output Modes section, and GPIO section
describe the behavior of the general-purpose pins when they are
configured for each function shown in Table 25.
The LFCSP options of the AD4697/AD4698 have one general-pur-
pose pin, BSY_ALT_GP0. The WLCSP option of the AD4698 has
four general-purpose pins: BSY_ALT_GP0, GP1, GP2, and GP3.
The BSY_ALT_GP0 pin on the LFCSP and the WLCSP options
have the same available functions, except that it is not used as the
SDO1 signal on the WLCSP (see Table 20 and Table 25).
When a general-purpose pin is configured for any function other
than a general-purpose input, it functions as a digital output. If
another device attempts to drive a general-purpose pin while it
is configured as a digital output, contention occurs and could
potentially damage the AD4697/AD4698. All AD4697/AD4698 gen-
eral-purpose pins are configured as digital inputs by default.
