Digital Inputs
The digital inputs are compatible with CMOS logic.
Supply current increases slightly when toggling the
logic inputs through the transition zone between
(0.3)(VDD) and (0.7)(VDD).
Microprocessor Interfacing
The MAX522 serial interface is compatible with
Microwire, SPI, and QSPI. For SPI, clear the CPOL and
CPHA bits (CPOL = 0 and CPHA = 0). CPOL = 0 sets
the inactive clock state to zero and CPHA = 0 changes
data at the falling edge of SCLK. This setting allows SPI
to run at full clock speeds (0.5MHz). If a serial port is
not available on your P, three bits of a parallel port can
be used to emulate a serial port by bit manipulation.
Minimize digital feedthrough at the voltage outputs by
operating the serial clock only when necessary.
