AmITX-IB-I

A.2 Program GPIO Function to Input

// before SIO programming, must enter config mode. //

SIOEnterConfig(); Enter SIO configure mode.

// bIndex = 07h as logical device selection register.

// bValue = 07h as logical device number (QM67 uses

GPIO 6)

SIOWrite(0x07, 0x07); Select to Logical Device 7

// bIndex = F4h as control register

// bValue = FFh as input enabled.

SIOWrite(0xF4, 0xFF); set all GPI/O to input

Read back GPIO Input Status

// bIndex = F5h as input register.

bValue = SIORead(0xF5); read back input register

// bValue = GPI/O input status.

// after SIO programming, must exit config mode. //

SIOExitConfig(); Exit SIO configure mode.
