GPIO Command
Write a command byte to the GPIO command register
to configure, write, or read the GPIOs, as detailed in
Table 12.
Write the command byte 00000011 to configure the
GPIOs. The eight SCLK cycles following the command
byte load data from DIN to the GPIO configuration reg-
ister in the MAX1220. The 16 SCLK cycles following the
command byte load data from DIN to the GPIO configu-
ration register in the MAX1257/MAX1258. See Tables
13 and 14. The register bits are updated after the last
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.
