Temperature Sensing, and GPIO Ports
CS rising edge. All GPIOs default to inputs upon power-
up.
The data in the register controls the function of each
GPIO, as shown in Tables 13–19.

Write the command byte 00000010 to indicate a GPIO
write operation. The eight SCLK cycles following the
command byte load data from DIN into the GPIO write
register in the MAX1020. The 16 SCLK cycles following
the command byte load data from DIN into the GPIO
write register in the MAX1057/MAX1058. See Tables 15
and 16. The register bits are updated after the last CS
rising edge.
