Starflow - Instructions
The Starflow instrument incorporates a Starlog compatible Micrologger which is a data recording
unit programmed using a computer. Its program resides in the first part of the logger’s main
memory (after the Hardware Registers and Buffer Control Table). It is defined by a user and
loaded into logger memory from the host computer.
The logger program is executed every logger scan (from 15 sec. to 5 min.). The first instruction in
the logger program is at Address 384. The Data Logger executes this program until an EXIT
instruction is encountered (opcode = 0).
