Standalone Mode (low-level

Overview
µISP can work with no connection to a PC (standalone mode). In standalone

(CONTROL connector). With this simple interface it is possible to start a project
(START) and check the result (OK/ERR).
Signals
The needed signals to control the instrument in standalone mode are located in the
“CONTROL” connector and are explained as below.
