STATUS AND CONTROL
MULTIFUNCTION PINS (M0 TO M7)
The AD9548 has eight digital CMOS I/O pins (M0 to M7) that
are configurable for a variety of uses. The function of these pins
is programmable via the register map. Each pin can control or
monitor an assortment of internal functions based on the contents
of Register 0200 to Register 0207. To monitor an internal function
with a multifunction pin, write a Logic 1 to the most significant
bit of the register associated with the desired multifunction pin.
The value of the seven least significant bits of the register defines
the control function, as shown in Table 24.

To control an internal function with a multifunction pin, write a
Logic 0 to the most significant bit of the register associated with
the desired multifunction pin. The monitored function depends
on the value of the seven least significant bits of the register, as
shown in Table 25.
