Status LEDs (LED Control Lines)

Every Tibbo device has two status LEDs — green and yellow — that indicate various device

modes and states. We refer to these LEDs as "Status Green" (SG) and "Status Red" (SR). These

LEDs are used:

By the Monitor/Loader (M/L)

By Tibbo OS (TiOS):

oWhen a Tibbo BASIC/C app is not running, these LEDs show the current state of the device

oWhen a Tibbo BASIC/C app is running, the status LEDs are under the app's control through

the pat. object (see the TIDE, TiOS, Tibbo BASIC, and Tibbo C Manual)

Many Tibbo programmable devices also have a "Status Yellow" (SY) LED. This LED is commonly

used to indicate that a network link has been established, but it serves other functions in

certain situations.
