+ | ==In Circuit Serial Programming.== | ||
+ | A means whereby microprocessors (PICs etc), may be programmed while mounted in the circuit they are intended to control. There are NO standard physical designs used for ICSP. Many MERG modules are provided with a common design connector to facilitate this, and a lead to connect the popular PICKIT programmer to the CBUS connector is [[: | ||

Name for means of linking the operation of points and signals such that signals can only show a proceed aspect when points are correctly set, and that points cannot be moved unless the signals over them are showing stop aspects. Interlocking can be mechanical, electrical using relays or carried out by computers. | Name for means of linking the operation of points and signals such that signals can only show a proceed aspect when points are correctly set, and that points cannot be moved unless the signals over them are showing stop aspects.

+ | =====ISR===== | ||
+ | Interrupt Service Routine. A subroutine called automatically by processor hardware when conditions within a peripheral cause an interrupt flag to be set and the matching interrupt enable flag is also set. Often there are priority settings also, a High priority interrupt cannot itself be interrupted whereas a Low priority interrupt can be interrupted by a High level one. |
