III-7.3 TRST ( hold amplifier (No. 32))
With control input hold set to 1, instantaneous input value x1 is stored and output at y1. With control input hold set to
0, output y1 follows input value x1.
The function has a ‘memory’. This means: after power-on, it continues operating with the y1 value which existed at
power-off, provided that the RAM data are still unchanged.
No parameters!
