2.4.8 First GPIO Port
All interface signals can be defined as GPIOs (General Purpose Input Output) or some special signals have
another function (Timer 4 to 7). For a detailed overview about these signals see the KTAM3874/pITX User's
Guide chapter 'Digital I/O Interface'. The signals are named GPIO21 to 24.
Note:
the operating systems do not support these special functions because the possible applications can
be too different.
The main menu shows following options:
Multiplexed GPIO/TIMER4+6 part
Multiplexed GPIO/TIMER5+7 part
The submenu allows the selection between:
gpio
timer
2.4.9 Second GPIO Port
All interface signals can be defined as GPIOs (General Purpose Input Output) or some special signals have
another function (UART2, UART4 or SPI3). For a detailed overview about these signals see the KTAM3874/
pITX User's Guide chapter 'Digital I/O Interface'. The signals are named GPIO12 to 18 resp. GPIO4 to 7.
The main menu shows following options:
Multiplexed GPIO/UART2 part
Multiplexed GPIO/UART4 part
Multiplexed GPIO/SPI3 part
