To update the track identifier bits, the 1P 241
requires 1 msec. for each specified start
The
1P 241 sets the synchronization bit
The 1P 241 dims the synchronization LED
The
1P 241 provides the NV value as actual value
The
1P 241 causes an interrupt if the NV value is
greater than an entered set value with interrupt
identifier, or alwavs when the NV interrurXs are
