Configuration
26 G24/H24 - Developer’s Kit August 31, 2009
General Purpose I/O (GPIO) - S120
The Developer Board can simulate all 8 G24/H24 GPIO1-GPIO8 states using the S120 switches.
Figure 2-15 shows the GPIO switches provided on the Developer Board, which are located on the
S120 component.
Figure 2-15: S120 Switches
GPIO signals mapping is shown in Table 2-14.
The G24/H24 GPIO lines can be configured both as output or input lines. The Developer Board
contains 8 LEDs, marked as GPIO1 through GPIO8, that indicate the GPIO state, regardless of its
configuration.
