The values stored in the connectors are normalized values, with a few exceptions (e.g. connectors for control words).
The value range of these connectors covers a percentage value range of:
? -200 % (8000H / 8000 0000H for double-word connectors) to
? +199,99 % (7FFFH / 7FFF FFFFH for double-word connectors).
100 % corresponds to the value 4000H (4000 0000H for double-word connectors).
无意间在老文件中发现一个很好的图示,分享一下。
例外,DCC中连接的实际值一般也是规格化后的百分比,写DCC的时候也要注意。
