S erial Data Output
The contents of the internal shift-register are output
serially on DOUT which allows for daisy-chaining of
multiple devices (see Applications Information as well
as data readback. The MAX5122/MAX5123 may be
programmed to shift data out of DOUT on the serial
clock’s rising edge (Mode 1) or on the falling edge
(Mode 0). The latter is the default during power-up and
provides a lag of 16 clock cycles, maintaining SPI,
QSPI, MICROWIRE, and PIC16/PIC17 compatibility. In
Mode 1, the output data lags DIN by 15.5 clock cycles.
During power-down, DOUT retains its last digital state
prior to shutdown.
User-Programmable Output (UPO)
The UPO feature allows an external device to be con-
trolled through the serial-interface setup (Table 1) there-
by reducing the number of microcontroller I/O ports
required. During power-down, this output will retain the
last digital state before shutdown. With
CLR
pulled low,
UPO will reset to the default state after wake-up.
