Figure 4-10 showsDIO<0..3> con figuredfor digital input and D IO<4..7>

configuredfor digital output. Digital input applications includ er eceiving

TTL signals and sensing externaldevice states such as the state of the

switch shownin the Figure 4-11. Digita loutp ut applications include

sending TTL signals and drivingexternal devices such as the LED shown

in Figure 4-11. Figure 4-11 depicts signal connections for three typical

digital I/O applications.
